Definitions
- the present invention relates to a rotating electrical machine control system that has a power conversion unit that boosts the output of a DC power supply and controls a rotating electrical machine for driving a vehicle. Moreover, it is related with a vehicle drive system provided with the said rotary electric machine control system.
- a motor as a rotating electrical machine operates based on the principle of generating a force (torque) by a magnetic field and an electric current.
- a force acts in the magnetic field, and so-called back electromotive force is generated.
- the counter electromotive force is generated in a direction that hinders the flow of current that generates torque, the current that flows in the magnetic field to rotate the motor decreases, and the force (torque) decreases. Since the counter electromotive force increases as the motor rotation speed increases, when the rotation speed reaches a certain value, the current generated by the counter electromotive force reaches the drive current, and the motor cannot be controlled.
- field weakening control is performed in which the field force that generates the magnetic field is weakened and the generation of the counter electromotive force is suppressed.
- field-weakening control is performed, the strength of the magnetic field is reduced to weaken the field force, and the maximum torque obtained is reduced.
- efficiency decreases due to increased loss.
- Patent Document 1 boosts the voltage of the battery that supplies driving power to the motor, and shifts the rotational speed to the field weakening control to a higher rotational speed.
- the voltage of the battery is boosted by the booster circuit (converter) according to the position of the target operating point of the motor set by the torque and the rotational speed. This makes it possible to shift the region for performing field-weakening control to the high output side (the high torque side and the high rotation speed side).
- the field of normal field control generally maximum torque control
- field-weakening control is not performed is expanded step by step by setting a plurality of boosted voltage values.
- Patent Document 2 discloses a technique for controlling so that an excessive current does not flow through such a booster circuit (power supply device). According to this technique, the torque command of the rotating electrical machine is limited so as not to exceed the output limit power of the booster circuit in accordance with the sum of the power consumption of the rotating electrical machine and the amount of change in the stored power of the smoothing capacitor.
- JP-A-10-66383 (3rd to 12th paragraphs, FIGS. 1 and 2 etc.) Japanese Patent Laying-Open No. 2005-210779 (Claim 1 etc.)
- the present invention was devised in view of the above problems, and can suppress power consumption so that the battery does not become overcurrent even when the voltage of the battery is boosted to drive the rotating electrical machine in a state where the power consumption is large.
- An object is to provide a rotating electrical machine control system.
- the characteristic configuration of the rotating electrical machine control system is as follows: A frequency converter that is interposed between a rotating electrical machine and a DC power source that supplies electric power to a rotating electrical machine for driving a vehicle, and at least converts the output of the DC power source into alternating current when the rotating electrical machine is powered; A voltage converter that is interposed between the DC power supply and the frequency converter and boosts the output of the DC power supply based on a boost command value set according to a target torque and a rotational speed of the rotating electrical machine; A control unit that controls the frequency conversion unit and the voltage conversion unit, and a rotating electrical machine control system comprising: The control unit is configured to limit an increase in the boost command value when the power consumption of the rotating electrical machine exceeds a predetermined power limit value.
- the power consumption of the rotating electrical machine may increase due to a response delay in feedback control.
- the power consumption of the rotating electrical machine is a value close to the allowable power of the DC power supply, the allowable power may be exceeded.
- the increase in the boost command value is limited when the power consumption of the rotating electrical machine exceeds the predetermined power limit value.
- the power limit value is a power that increases within a delay time until the control unit acquires the boosted voltage value boosted by the voltage conversion unit from an allowable power that the DC power supply can output. It is preferable to set as a value obtained by subtracting.
- a value obtained by subtracting the power increasing within the delay time from the allowable power that can be output by the DC power supply is set as the power limit value. Therefore, it is possible to satisfactorily suppress an excessive current drawn from the DC power source due to an increase in power consumption accompanying a response delay such as a detection delay of the voltage value after boosting.
- the rotating electrical machine control system includes: The controller determines a boost command value that is set according to the target torque and rotation speed of the rotating electrical machine, and the output of the DC power supply is set on condition that the boost command value exceeds the voltage of the DC power supply.
- the voltage conversion unit includes a series circuit of an upper switching element connected to the plus side and a lower switching element connected to the minus side.
- a dead time is provided in which both the upper switching element and the lower switching element are controlled to be in an off state in order to prevent a short circuit between the positive side and the negative side. It is done. Due to the influence of this dead time, a predetermined voltage range corresponding to the system cannot be boosted in a situation where the boost target value is rising. Then, after the transition from the non-boosting control to the boosting control, the output of the voltage conversion unit rapidly increases greatly beyond this voltage range.
- the possibility that the increase in the boost command value is limited beyond the limit value is greatly suppressed.
- the transition from non-boosting control to boosting control is necessary when an increase in torque or rotational speed is required. Since the transition from the non-boosting control to the boosting control is not hindered, for example, when the rotating electrical machine is used in a vehicle drive system, drivability is improved.
- the power consumption of the rotating electrical machine is acquired using the target torque and the rotational speed of the rotating electrical machine.
- the power consumption of the rotating electrical machine is not acquired based on the actual measurement values of the voltage and current, the power consumption of the rotating electrical machine can be acquired without being affected by the delay caused by the sensor that measures the voltage and current. Therefore, when the power consumption of the rotating electrical machine exceeds the power limit value, this can be detected quickly and the increase in the boost command value can be limited. As a result, the direct current power supply is well suppressed from being overcurrent.
- the reference power is set as a power obtained by subtracting the increased power generated when the target torque is maximum from the allowable power.
- Rotating electrical machines increase in power consumption as the target torque increases. Therefore, the difference between the allowable power and the power consumption decreases as the target torque increases. Further, the increased power generated transiently due to the response delay with respect to the boosted voltage that suddenly increases during the transition from the non-boosting control to the boosting control increases as the target torque increases.
- the increased power when the target torque is maximum is the maximum value among the generated increased power. Therefore, the power obtained by subtracting the increased power from the allowable power is the smallest when the target torque is the maximum.
- the step-up command value in the rotating electrical machine control system defines the voltage value of the output of the voltage conversion unit or the step-up rate in the voltage conversion unit, Preferably, the control unit limits the increase in the boost command value by fixing the boost command value.
- the boost command value When the boost command value is fixed, an increase in the voltage after boost, which is the output of the voltage conversion unit, is suppressed, so that an increase in power consumption of the rotating electrical machine is suppressed.
- the boost command value is a value that defines the output voltage of the voltage converter
- the boosted voltage is held constant, and an increase in power consumption of the rotating electrical machine is suppressed.
- the boost command value defines the boost rate by the voltage converter
- the boosted voltage is suppressed to a certain value or less.
- the step-up rate in the voltage conversion unit is fixed, and when the DC voltage that is the input voltage to the voltage conversion unit decreases, the value of the output voltage from the voltage conversion unit also decreases. Therefore, when the boost command value defines the boost rate by the voltage converter, the boosted voltage is suppressed to a certain value or less. In this way, by fixing the boost command value, an increase in the voltage after boost, which is the output of the voltage converter, is suppressed. As a result, it is possible to prevent an excessive current from being drawn from the DC power source due to an increase in power consumption accompanying the detection delay of the voltage value after boosting.
- control unit of the rotating electrical machine control system is configured such that the voltage conversion from the non-boosting control supplied to the frequency conversion unit via the voltage conversion unit without boosting the output of the DC power supply. It is preferable to limit the increase of the boost command value by prohibiting the shift to the boost control that is boosted by the block and supplied to the frequency converter.
- the output of the voltage conversion unit increases rapidly. Then, due to the response delay with respect to the rapid voltage rise, the rising power is generated transiently, and a large current may be drawn from the DC power source to cause an overcurrent.
- the output of the voltage conversion unit does not increase rapidly. Therefore, it can be suppressed that a large amount of current is drawn from the DC power source due to an increase in power consumption accompanying a delay in detection of the voltage value after boosting.
- the frequency converter of the rotating electrical machine control system according to the present invention is input based on a DC voltage value input to the frequency converter and a modulation rate set according to the target torque.
- the converted direct current is converted into alternating current.
- the modulation factor When the modulation factor is set using the measured value of the boosted voltage by the voltage converter, the modulation can be performed with high accuracy based on the actual voltage. In normal times, the power consumption of the rotating electrical machine is unlikely to change suddenly. Therefore, setting the modulation factor using the measured value of the boosted voltage is preferable because the rotating electrical machine can be controlled with low loss.
- the power consumption of the rotating electrical machine suddenly increases and exceeds the power limit value, as described above, it is suppressed by the determination based on the power limit value. In determining whether or not the power limit value is exceeded, not only the power consumption acquired from the actual measurement value, but also a value acquired using the target torque and the rotation speed of the rotating electrical machine can be used.
- the rotating electrical machine is controlled using measured values that can be controlled with high accuracy and low loss.
- the rotating electrical machines can be controlled using values other than the measured values. Therefore, good control corresponding to the situation is possible without being affected by response delay.
- the rotating electrical machine includes a first rotating electrical machine and a second rotating electrical machine, A power distribution mechanism that distributes a driving force generated from a driving source other than the first rotating electric machine and the second rotating electric machine, wherein one driving force distributed by the power distributing mechanism is applied to a wheel, and the other driving force; Is transmitted to the first rotating electrical machine, and the driving force generated by the second rotating electrical machine is transmitted to the wheels.

- a decrease in the boost command value may be permitted and only an increase may be prohibited.
- the limit flag when the estimated power reaches the change rate limit threshold TH, the limit flag becomes active.
- the restriction flag remains active until the estimated power falls below the change rate restriction release threshold TL.
- the change rate restriction release threshold value TL is set to a value smaller than the change rate restriction threshold value TH, and the restriction flag has hysteresis.

As described above, when the power consumption (estimated power) exceeds the change rate limit threshold TH, the limit period is reached. Therefore, the change rate limit threshold TH corresponds to the power limit value of the present invention.
- the change rate restriction release threshold TL also corresponds to the power restriction value of the present invention.
- the change rate limiting threshold TH is obtained from the allowable power that can be output by the battery B (W BMAX, which will be described later). It is preferable to set as a value obtained by subtracting.
- the voltage converter 4 is controlled in a state where the boost is restricted (# 6). ). That is, boosting by the voltage conversion unit 4 is performed based on the boost command value limited as described above.
- the boost command value defines a target voltage indicating the voltage V C after boosting, and the limitation on the change in the boost command value fixes the boost command value (target voltage). It corresponds to.
- the step-up command value defines the step-up rate in the voltage conversion unit 4, and may limit the change in the step-up command value (step-up rate) by fixing the step-up rate.
- the voltage V C changes as follows.
- the estimated power (power consumption) is large enough to exceed the change rate limit threshold TH, a large amount of current is drawn from the battery B. Therefore, the voltage V B of the battery B tends to decrease.
- the step-up rate is fixed, the output of the voltage conversion unit 4 also decreases as the battery voltage V B decreases.
- the voltage V B of the battery B is constant during the period when the limit flag is active, the output of the voltage conversion unit 4 is also maintained at a constant value. In this way, by limiting the increase in the boost command value, at least the output voltage V C of the voltage conversion unit 4 is not increased, so that an increase in power consumption can be suppressed.
- a portion indicated by a broken line in the waveform of the boosted voltage V C shown in the lower part of FIG. 5 indicates a boost command value defined as the target voltage.
- the change rate restriction release threshold TL is set to a value that does not exceed the allowable power (W BMAX (see FIGS. 8 and 10), which will be described later) due to the rapid increase in the voltage V C and the power consumption rapidly increasing.
- W BMAX allowable power
- FIG. 6 shows an example in which the voltage conversion unit 4 shifts from non-boosting control to boosting control within a period in which the boost command value is limited.
- the voltage V B of the battery B is an output voltage V C of the voltage conversion unit 4, restriction flag Similarly voltage V B also becomes active Towards the output voltage V C of the voltage converter 4.

- W BMAX allowable power
- Boostable power (reference power) W S ” described later is suitable.
- the rate of increase in the boost command value per unit time is the maximum during the transition from the non-boost control to the boost control. Therefore, it is considered that the potential difference at which the voltage V C increases after the limit period elapses is larger at the time of transition from non-boosting control to boosting control. Therefore, a limit flag (limit period) during boost control and a limit flag (limit period) during non-boost control may be provided separately. Both the change rate restriction threshold value TH and the change rate restriction release threshold value TL may be set separately, or the change rate restriction threshold value TH uses a common value, and the change rate restriction release threshold value TL has a different value. It may be used. In the latter case, it is preferable that the change rate restriction release threshold TL during non-boosting control is set to a value smaller than the change rate restriction release threshold TL during boost control.

- the waveform schematically shown in the middle part of FIG. 7 indicates the modulation rate of the frequency converter 5.
- the waveform schematically shown in the lower part of FIG. 7 indicates the current (I MG1 or I MG2 ) of the rotating electrical machine.
- the switching elements 4c and 4d of the voltage conversion unit 4 are both controlled to be in the off state, so that boosting cannot be performed. For this reason, a predetermined voltage range corresponding to each system cannot be boosted in a situation where the boost target value is increasing.
- the output of the voltage conversion unit 4 increases rapidly and greatly exceeds the voltage range.
- the rotating electrical machine drive device In is provided with a voltage sensor (not shown), and the voltage V B of the battery B and the voltage V C after being boosted by the voltage conversion unit 4 are measured, and the result is acquired by the TCU 10. .

That is, as shown schematically by the solid line in the upper part of FIG. 7, in fact despite the voltage V C is rapidly increased, the TCU 10, the voltage V C gradually rises as indicated by a broken line Detects that
- the TCU 10 calculates a modulation rate for conversion to AC according to the acquired voltage V C , that is, the voltage value of the DC voltage on the input side of the frequency converter 5. Specifically, the duty of PWM control is calculated. At this time, since the voltage V C is recognized as a value lower than the actual value, a modulation rate higher than a necessary modulation rate is calculated, and the frequency converter 5 is PWM-controlled according to this modulation rate. As schematically shown by the solid line in the middle stage of FIG. 7, the modulation rate is gradually lowered as shown by the broken line, although the modulation rate actually needs to be suddenly lowered.
- the rotating electrical machine is driven by receiving an excessive power supply with respect to the target torque, and the motor current flowing through the rotating electrical machine (for example, the motor current I MG2 of the second rotating electrical machine MG2 ) increases.

- the voltage V C of the output of the voltage conversion unit 4 since a battery voltage V B, the voltage V C of the output of the voltage conversion unit 4, as shown in the lower part of FIG. 8, the battery B Decreases as the current I B increases.
- the boost command value of the voltage conversion unit 4 is determined according to the rotation speed of the rotating electrical machine and the target torque, and this boost command value is the boost target value E after boosting.
- the boost target value E When the rotating electrical machine is driven with a high load, the boost target value E also tends to increase. Therefore, at time t, the boost target value E exceeds the output voltage V C of the voltage converter 4, and the voltage converter 4 Starts the boost operation.
- the boost target value E and the boost impossible voltage V D at the transition boundary K2 for boosting the voltage V B of the battery B are predetermined according to the system configuration of the rotating electrical machine drive device In. Is the value of Therefore, the voltage V B of the battery B at the time of shifting from the non-boosting control to the boosting control is almost a fixed value. For this reason, the upper limit value, that is, the allowable value can be defined by the battery power W B (allowable power W BMAX ).
- FIG. 9 is a correlation diagram between the torque of the rotating electrical machine and the increased electric power showing the measurement results. As is apparent from FIG. 9, the increased electric power increases as the torque increases. Therefore, the increased electric power when the torque of the rotating electrical machine is maximum (T MAX ) becomes the maximum value ( ⁇ MAX ) of the increased electric power.

- the boostable power W S corresponds to the reference power of the present invention.
- the boostable electric power W S obtained by subtracting the increased electric power ( ⁇ ) from the allowable electric power W BMAX is the smallest when the target torque is the maximum (T MAX ). If the boosted electric power W S to set the shift boundary K as a reference, regardless of the magnitude of the target torque, favorably suppress the generation of the overcurrent of the battery B due to transient voltage increase that occurs at the beginning of the step-up It becomes possible.
- the V / I characteristic of the battery B and boost electric power W S, step-up start voltage E S is obtained.
- the boost target voltage E T to be given as the boost command value to the voltage conversion unit 4 is a value obtained by adding the boost impossible voltage V D to the boost start voltage E S.
- the voltage conversion unit 4 is provided on the condition that the target torque and the rotation speed of the rotating electrical machine exceed a predetermined transition boundary K2 (K) set based on the correlation between them.
- a transition is made from non-boosting control to boosting control. If the transition boundary K2 (K) is set in a region where the power consumption of the rotating electrical machine does not reach the allowable power WBMAX even when the increased power is generated, the battery B is excessive in transition from the non-boosting control to the boosting control. There is no current. That is, transient and occurs increased electric power (e.g.
- delta MAX of the maximum value) with respect to the step-up electric power W S is a power obtained by subtracting from the battery B can be output allowable power W BMAX during migration, consumption of the rotating electrical machine may shift boundary K is set in a region where power is less boosting electric power W S.
- FIG. 11 is an explanatory diagram for setting the transition boundary K in the correlation diagram between the rotational speed and torque of the rotating electrical machine.
- FIG. 11 corresponds to FIG. 3, but for the sake of simplicity, only the torque region in the positive direction is shown.
- a transition boundary K2 is a boundary provided to start boosting in order to perform normal field control of the rotating electrical machine without shifting to the field weakening control without considering the increased power as described above.
- the region on the upper right side of the boundary line corresponding to the boostable power W S that is, the direction in which the torque increases and the direction in which the rotational speed increases are regions where the power consumption is larger than the boostable power W S. .
- the shift boundary K2 is also set in the area power consumption is greater than the boosted electric power W S. Therefore, depending on the rotational speed and target torque of the rotating electrical machine at the start of boosting, the battery power W B exceeds the allowable power W BMAX of the battery B, and a current exceeding the allowable current I BMAX is drawn from the battery B and becomes an overcurrent. Have potential. Therefore, shift boundary boundaries for initiating booster toward the boost target voltage E T at start of boost is set only in the lower left side of the region than the boundary line corresponding to the boosted electric power W S in the drawing K3 Set as (K). In other words, transient and occurs increased electric power (e.g.
- delta MAX of the maximum value) with respect to the step-up electric power W S is a power obtained by subtracting from the battery B can be output allowable power W BMAX during migration, consumption of the rotating electrical machine shift boundary K3 (K) is set in a region where power is less boosting electric power W S.

- the transition boundaries K2 and K3 are different curves. It can be seen that in the left side of FIGS. 12A and 12B, particularly in the region indicated by the ellipse in FIG. 12B, the boost target voltage E T has a voltage value higher than that in FIG.
- the transition boundary K is a transition boundary K3 set in a region where the power consumption of the rotating electrical machine is lower than the boostable power (reference power) W S .
- the non-boosting control is switched to the boosting control after the limit period has elapsed. It is possible to reduce the possibility that the power consumption exceeds the allowable power W BMAX by shifting.
- the rate of change restriction is canceled to ensure that the boosted voltage V C suddenly rises from non-boost control to boost control and that power consumption does not exceed the allowable power WBMAX.
- the change rate restriction release threshold value TL is a value that is too low as a release threshold value when the boost control is already performed and the restriction period is provided, and thus the restriction period is unnecessarily prolonged.
- it is possible to use different change rate restriction release thresholds TL depending on whether boost control or non-boost control is being performed at the start of the limit period it is better not to provide such condition division as much as possible.
