Definitions
- the invention relates to a method for controlling an electromechanical actuator. It relates in particular to an actuator for controlling an internal combustion engine.
- a known actuator (DE 195 26 683 AI) has an actuator, which is designed as a gas exchange valve, and one
- the actuator has two electromagnets, between each of which an armature plate can be moved against the force of a restoring means by switching off the coil current on the holding electromagnet and switching on the coil current on the catching electromagnet.
- the coil current of the respective capturing electromagnet is kept constant at a predefined catch value I_MAX for a predefined period of time, then switched off for a predefined switch-off time, and then regulated to a hold value by a two-point controller with hysteresis. From the time course of the coil current during the switch-off time, a bounce of the armature plate on the respective electromagnet is recognized and a corresponding correction of the catch value is carried out.
- the coil current cannot be set to the corrected catch value until the next capture operation.
- the armature plate can possibly move so far away from the capturing electromagnet that sufficient holding force can no longer be applied by the holding current to bring the anchor plate into contact with the capturing electromagnet.
- the object of the invention is to provide a method for controlling an actuator which is simple and which ensures that the anchor plate is captured.
- the invention is solved by the features of claim 1.
- the solution has the advantage that the first catch value can be predefined in such a way that a desired speed profile of the anchor plate is set and that the second catch value can be set in such a way that the anchor is securely caught and the anchor is prevented from falling into a rest position.
- the second catch value depends on the speed of the anchor plate before the threshold value is exceeded. This has the advantage that the second catch value can be specified in such a way that on the one hand a low heat loss is generated, but on the other hand the anchor plate is captured safely.
- the second catch value is specified as the target value if the
- Position of the anchor plate a further threshold value, the amount of which is smaller than the threshold value K0, K5, longer than a predetermined additional time period. This ensures that the anchor plate is securely caught if the force caused by the first catch value is not sufficient for the position of the anchor plate to exceed the threshold value K0, K5.
- FIG. 1 shows an arrangement of an actuator in an internal combustion engine
- FIG. 2 shows the position of the armature plate and output signals of a comparator device plotted over time t
- FIG. 3 shows a block diagram of a control device for controlling the actuator
- Figure 4 shows the time course of the voltages
- An actuator 1 ( Figure 1) comprises an actuator 11 and an actuator, which is designed for example as a gas exchange valve and has a shaft 121 and a plate 122.
- the actuator 11 has a housing 111 in which a first and a second electromagnet are arranged.
- the first electromagnet has a first core 112, in which a first coil 113 is embedded in an annular groove.
- the second electromagnet has a second core 114, in which a second coil 115 is embedded in a further annular groove.
- the first core 112 has a recess 116a, which forms a guide for the shaft 121.
- the second core 114 has a further recess 116b, which also serves as a guide for the shaft 121.
- An anchor plate 117 is movably arranged in the housing 111 between the first core 112 and the second core 114.
- a first spring 118a and a second spring 118b bias the anchor plate into a predetermined rest position R.
- Actuator 1 is rigidly connected to a cylinder head 21.
- An intake port 22 and a cylinder 23 with a piston 24 are assigned to the cylinder head 21.
- the piston 24 is coupled to a crankshaft 26 via a connecting rod 25.
- a control device 3 which detects signals from the sensors and generates control signals for the control device.
- the sensors are, as a position transmitter 4, which detects a position X of the armature plate 117, as a first ammeter 5a, which detects the actual value I_AV1 of the current through the first coil 113, a second ammeter 5b, which detects an actual value I AV2 of the current through the second coil 115, as a speed sensor 27, which detects the speed N of the crankshaft, or as a load detection sensor 28, which is preferably an air mass meter or a pressure sensor.
- other sensors may also be present.
- a comparator device 7 which generates a pulse signal depending on the detected position X and predetermined threshold values.
- the function of the comparator device 7 is explained in more detail below with reference to FIG. 2.
- Drivers 6a, 6b are provided which amplify the control signals of the control device 3.
- the time course of position X of the anchor plate is plotted in FIG. 2a.
- the comparator device 7 has six analog threshold value comparators, each of which changes its output signal at one of the threshold values K0, Kl, K2, K3, K4, K5.
- the pulse signals of the comparator device which are plotted in FIGS. 2b and 2c, then arise through a logical combination of the threshold value comparators.
- the threshold values K0, K1, K2 are predetermined at the same distance from the rest position R of the anchor plate as the threshold values K3, K4 and K5.
- the threshold values are, for example, the following relative distance values, which are based on the distance between the contact surface of the armature plate in the first electromagnet and the contact surface in the armature plate for the second electromagnet: K0 at 2%, Kl at 5%, K2 at 20%, K3 at 80%, K4 at 95% and K5 at 98%.
- the timer 8 determines the pulse durations of the pulses of the pulse signals.
- the pulse duration of the pulse which is predetermined by the threshold values K3 and K4, is assigned the time duration T_C2.
- the time period T_C2 is a measure of the average speed of the armature between the threshold values K3 and K4.
- the timer also determines the time period T_C3, which is predetermined by the time interval when the position X is exceeded from the threshold values K4 and K5.
- the determination of the time period T_02, T_03 is carried out analogously to the determination of the time period T_C2 and T_C3.
- FIG. 3 shows a block diagram of the control device 3 for controlling the electromechanical actuator 1.
- a first catch value I_F1 is determined from a map, specifically as a function of the speed N and the air mass flow MAF.
- the values of the map are determined on an engine test bench or by simulations so that heat losses in the respective coil are low.
- the difference between an actual time period T_C3 and the target value T_C3 * of the time period is determined in a summing point SI.
- a predefined setpoint T_C2 * is then adapted depending on the difference that was determined in the summing point SI.
- the difference between the setpoint T_C2 * and the actual time period T_C2 is calculated in a summing point S2.
- a block B3 comprises an integrator which, depending on the difference between the target value T_C2 * and the actual time T_C2, calculates a correction value with which the first catch value I_F1 is corrected in the third summing point.
- a second catch value I_F2 is determined in a block B4.
- the second catch value I_F2 is either fixed or stored in a characteristic curve depending on the difference between the actual time period T_C3 and the target value T_C3 * of the time period. If the second catch value I F2 is fixed, it has this has the advantage that the determination of the second catch value I_F2 is less computation-intensive. If the second catch value I_F2 is determined via the characteristic curve as a function of the difference between the actual time period T_C3 and the target value T_C3 * of the time period, the heat losses from the coil which is energized in each case are significantly reduced.
- the characteristic curve preferably has the shape shown in FIG. 5. If the difference between the actual time period T_C3 and the target value T_C3 * of the time period is zero, then the second catch value I_F2 has a minimum value. If the difference is less than zero, the second catch value I_F2 increases in order to generate a sufficient force that dampens a bouncing process and prevents the armature from bouncing into the rest position. If the difference is greater than zero, the second catch value is also increased in order to prevent the anchor plate from falling into the rest position R.
- a holding value I_H is determined as a function of the speed N and an air mass flow MAF from a map.
- a time period T_F_OFF is determined in a block B6, depending on the difference between the target value T_C2 * and the actual time period T_C2.
- the time period T_MAX, the time period T_F_OFF and other operating variables of the internal combustion engine it is determined whether the first catch value I_F1, the second catch value I_F2, the hold value I_H or a zero value is the target value for a controller B8 .
- the position X of the anchor plate is determined indirectly via the actual time periods T_C2, T_C3, T_02, T_03.
- the setpoint value for the controller B8 changes from the first catch value I_F1 to the second catch value I_F2.
- the first condition is preferably met if the amount of the position X of the anchor plate exceeds the threshold value K5, K0, this becomes indirect recognized that the timer 8 has forwarded a new actual time period T_C3 to the control device 3,
- the controlled variable of the controller B8 is the current through the coil 113, 115 to be energized.
- the difference between the desired value determined in block B7 and the actual current I_AV1, I_AV2 through the coil 113, 115 is the control difference of the controller B8.
- the controller is preferably designed as a two-point controller with hysteresis.
- the manipulated variable of the controller is a voltage signal U1, U2, which is fed to the driver 6a or 6b, which amplifies it and supplies it to the first or second coil 113, 115.
- FIG. 3 shows the block diagram as an example for the calculation of the control signal for the first coil 113.
- the control signal for the second coil 115 is calculated analogously, only the time periods T_C2 and T_C3 are to be replaced by the time periods T 02 and T 03.
- FIG. 4a shows the manipulated variable of controller B8, which is a first voltage signal U1 with which the first coil 113 is excited, or a second voltage signal U2 with which the second coil 115 is excited.
- FIG. 4b shows the assigned time course of the actual value I_AV1 of the current through the first coil 113, and punctures the time course of the actual value I_AV2 of the current through the second coil 115.
- FIG. 4c shows the position X of the anchor plate plotted over the time t.
- the desired value for the current through the first coil 113 is the first catch value I_F1.
- the second catch value I F2 is then specified as the setpoint for the controller B8.
- T_F2 is the target value of controller B8, the second catch value.
- a second condition is met if the time period from the specification of the second catch value I_F2 is greater than the time period T_F2.
- time period T_F2 depends on the speed of the armature plate 117 before the threshold value K5 is exceeded.
- the time period T_C3 is a measure of the speed of the anchor plate before the threshold value K5 is exceeded.
- the second catch value I_F2 is advantageously chosen to be larger than the first catch value I_F1. This ensures that the armature plate is securely caught by the first electromagnet.
- the hold value I_H is specified as a setpoint for the controller B8 up to a time t 4 .
- the hold value can be selected to be very low, namely lower than the second catch value I_F2, since the armature is statically applied to the first electromagnet, while the hold value I_H is the setpoint for the controller B8.
- the zero value (for example zero amperes) is specified as the target value for the current through the first coil 113.
- the armature plate then swings in the direction of the second electromagnet.
- current is then supplied to the second coil from time t 5 , namely that the first catch value I_F1 is specified as the target value for the controller B8, and the controller B8 then generates the second voltage signal U2.
- the actuator can also be designed as an injection valve.
- the method can be executed as a program by a microprocessor. However, it can also be implemented by a logic circuit or an analog circuit arrangement.
- the controller can also be designed, for example, as a single-point controller with a timing element or as a pulse width modulation controller.
- a controller can also be provided for each coil 113, 115.
- a rectifier can also be provided, which rectifies the signal of the position transmitter 4, the rest position R then having the value zero.
- the comparator device then accordingly has only three threshold value comparators, each of which changes its output signal at the threshold value K0 or K1 or K3.
- the stopping value can also be specified as the setpoint for the current through the first coil after a predetermined period of time after the zero value has been specified as the setpoint for the current through the second coil.
- a particularly low impact speed of the anchor plate on the respective core 112, 114 can be achieved if the first catch value I_F1 is set to the zero value for a period T_F_OFF after a time t la .
- the time period T_F_OFF is calculated in block B6 depending on the difference between the target value T_C2 * and the actual time period T_C2. Since the deviation of the actual time period T_C2 from the target value T_C2 * is a measure of the deviation of the expected impact speed, the impact speed of the armature on the core can be set to the desired value by switching off the current through the coil for the time period T_F_OFF.
