Description

High-dynamic-response flux-weakening speed-increasing method for permanent magnet synchronous motor
Technical Field
The invention belongs to the technical field of motor drive control, and relates to a high-dynamic-response flux-weakening speed-expanding control method for a permanent magnet synchronous motor.
Background
The magnetic field acting with the armature in the permanent magnet synchronous motor is generated by the permanent magnet, and the permanent magnet synchronous motor has the characteristic of non-adjustability. Therefore, the permanent magnet synchronous motor cannot realize speed expansion operation by directly adjusting the magnetic field generated by the permanent magnet, and needs a weak magnetic control algorithm to realize the speed expansion operation.
In the traditional flux weakening control method, the distribution of the d-axis and q-axis current given values depends on the precise model equation of the motor to a great extent, such as a maximum torque-current ratio curve, a voltage and current limit equation and the like, and the flux weakening degree is adjusted on the basis of a voltage threshold. In the dynamic process, the method is not only limited by inaccurate model parameters, but also the voltage and current limit equations based on the steady-state performance are not completely suitable for the transient working condition, so that the high-dynamic-response flux weakening control is difficult to realize.
In practical application, high dynamic speed expanding performance is required in many occasions, for example, when an underwater vehicle propelled by a propeller is in emergency danger avoidance, a propelling motor is required to drive the propeller to expand the speed to run to reach the maximum possible speed so as to accelerate or brake. The traditional vector control method adopts a control strategy that d-axis current is zero, and only can reach rated speed without speed expansion capability. The traditional flux weakening control is mostly aimed at the steady-state performance and does not meet the requirement on quick response.

Example 1: speed expansion control effect of underwater vehicle propulsion propeller
The embodiment 1 shows the flux weakening and speed increasing effect of one permanent magnet synchronous motor driving underwater propeller load. Fig. 3 shows the control effects of the conventional vector control and the method of the present invention, wherein the conventional vector control has the rotational speed, current and voltage responses as shown in fig. 3(a), (c) and (e), respectively, and the method of the present invention has the rotational speed, current and voltage responses as shown in fig. 3(b), (d) and (f), respectively. When the rotating speed is given to be 800rpm, the rotating speed of the motor is only 670rpm when the inverter voltage u reaches the maximum under the traditional vector control, the maximum rotating speed of the method can reach the given rotating speed of 800rpm, and the response time is within 2 s. The response time of the traditional vector control rotating speed ring reaching 670rpm is about 0.7s, the flux weakening speed expansion method of the method is activated at 600rpm and reaches 715rpm at 0.7s, and the dynamic response of the rotating speed is superior to that of the traditional vector control. Although the acceleration time is influenced by the great increase of the load torque brought by the acceleration of the propeller, the response time is less than 2s when the flux weakening control method reaches 800rpm, and the dynamic performance of speed control during speed expansion is similar to that of the traditional vector control.
According to the characteristics of the propeller, the output power of the propeller is proportional to the third power of the rotating speed, under the traditional vector control method, the propeller can only output 2038W power at maximum, and the propeller can output 4142W power by using the method of the invention. For the underwater vehicle driven by the propeller in the embodiment, the method can realize high dynamic speed expansion, and the output power of more than twice of vector control is achieved within 2s, so that the high thrust of quick response is generated, and the emergency risk avoiding and emergency braking performance of the underwater vehicle is improved.

When the actual rotating speed omega exceeds 600rpm in the actual control process (t is 0.4s), omega & gt omega is satisfiedthWhen the condition of the weak magnetic ENABLE signal ENABLE is met, the weak magnetic function ENABLE of the motor is enabled, the d-axis speed regulator is activated at the same time, and the d-axis current is given by

The change direction is negative, and the change direction can be realized by simple processing such as adding a negative sign to the output quantity, measuring a negative error quantity, or setting the parameter of the controller to be negative. As can be seen from FIGS. 3(b), (d), after 0.4s the flux weakening function is activated, idAnd the magnetic flux is reduced from 0A to-29A within 4ms, the magnetic flux rapidly enters a weak magnetic operation state, and the weak magnetic functional module can effectively work.

The resultant voltage is 1 at maximum, indicating the maximum voltage that the inverter can output. A composite voltage exceeding 1 is not only impossible to achieve, but also affects the stability of the control. Compared with fig. 3(e), the synthetic voltage amplitude limiting module of the method of the invention can effectively ensure the d-axis voltage amount required by field weakening, and can ensure that the maximum synthetic voltage does not exceed 1, namely the output voltage is always effective.

FIG. 4 shows the control effect of the conventional vector control and the method of the present inventionAs a result, the conventional vector control speed, current and voltage responses are shown in fig. 4(a), (c) and (e), respectively, and the conventional vector control speed, current and voltage responses are shown in fig. 4(b), (d) and (f), respectively. When the rotating speed is set to be 1200rpm, the rotating speed of the motor is only 720rpm when the inverter voltage u reaches the maximum under the traditional vector control, the actual rotating speed of the method can reach the set rotating speed of 1200rpm, and the response time is within 2 s. The weak magnetic control enabling threshold value of the method is

Given by the speed regulator. The method of the invention can be seamlessly switched from the traditional vector control to the weak magnetic control, and the dynamic performance of the speed control during speed expansion is similar to that of the traditional vector control.
As can be seen from FIGS. 4(b) and (d), the field weakening function is activated for about 0.4s, idAnd the magnetic flux is reduced from 0A to-26A within 2ms, the magnetic flux rapidly enters a weak magnetic operation state, and the weak magnetic functional module can effectively work.

Figure BDA0001579941110000081
The maximum synthesized voltage is 1, indicating that the inverter isThe maximum voltage that can be output, a combined voltage exceeding 1, is not only impossible to achieve, but also affects the stability of the control. As can be seen from fig. 4(e), the synthesized voltage amplitude limiting module of the method of the present invention can effectively ensure the d-axis voltage amount required for flux weakening, and can ensure that the maximum synthesized voltage does not exceed 1, i.e., the output voltage is always effective.
In conclusion, the method takes the given rotating speed and the feedback threshold value of the rotating speed as the conditions of the enabling of the flux weakening control, after the flux weakening function is enabled, the given d-axis current and the given q-axis current are adjusted by corresponding speed regulators, and the amplitude limit of the synthesized voltage value of the reserved d-axis voltage is used for ensuring the implementation of the flux weakening function d-axis voltage value during speed expansion. Therefore, the method of the invention can realize high dynamic flux weakening speed expansion control with performance similar to that of the traditional vector control speed ring, has no oscillation in the control process and can realize seamless switching with the traditional vector control.
Example 3: compatibility of weak magnetic control of non-weak magnetic area and traditional vector control
The method starts the weak magnetic control by the threshold comparison condition of the given rotating speed and the actual rotating speed, and when the threshold of the rotating speed is set to have a certain margin, the weak magnetic control is started in a non-weak magnetic region, so that the weak magnetic control can be compatible with the traditional vector control to avoid the oscillation and control abnormality.
This embodiment shows the compatibility of the weak magnetic control of the method of the present invention to the conventional vector control when the non-weak magnetic region operates. When the conventional vector control is adopted, the motor speed can reach 720rpm under the condition that the inverter voltage u reaches the maximum, and the speed, current and voltage responses of the motor are shown in fig. 4(a), (c) and (e).
The weak magnetic control enabling threshold value given by the embodiment is

Figure BDA0001579941110000094
The rotational speed, current, and voltage responses given by the rotational speed regulator are shown in fig. 5(a), (b), and (c). As can be seen from FIGS. 5(a), (b), and (c), although the flux-weakening control is always activated after the time of 0.6s, the d-axis current drops at the time of 0.6s, and returns to 0 again at the time of 0.8s after being adjusted for a short time, so as to reach the same level as the conventional idThe same control effect is obtained when the value is 0. In the rotating speed response, except for the overshoot of 0.4%, the method is basically the same as the traditional vector control dynamic response when the flux weakening function is activated, which shows that the flux weakening control method of the invention can automatically adjust according to the situation in the activated state, can automatically achieve the same effect as the traditional vector control in the non-flux weakening area, and has good compatibility with the traditional vector control.
