Description
Technical Field
The invention relates to the field of motor control, in particular to a torque control method of a switched reluctance motor.
Background
The switched reluctance motor speed regulating system has the advantages of simple structure, reliable work, high mechanical strength, high efficiency, energy conservation, high speed regulating precision, small starting current, frequent forward and reverse rotation operation and the like, and has wide application prospect in the fields of aerospace, electric automobiles, household appliances, industrial transmission and the like. The modular power converter has the advantages of universalization, standardization, serialization and the like, and has potential advantages in the aspects of improving the integration level of a switched reluctance motor driving system, reducing the cost and the like. However, due to the application of the modular power converter, the switched reluctance motor windings are in star connection and have the characteristic of bipolar excitation, the inductance is the superposition of two-phase windings, the phase current is slowly established, the torque cannot well track the reference value of the switched reluctance motor, the traditional direct instantaneous torque control method is not applicable any more, the torque pulsation of the switched reluctance motor is large, the vibration and the noise are still obvious, and the wider application of the switched reluctance motor is limited to a great extent.
The torque distribution function control strategy of the switched reluctance motor aims at keeping the synthesized instantaneous torque constant, and the expected torque of each phase winding at different positions is distributed through the torque distribution function, so that the method is an effective method for improving the torque tracking capability. The torque distribution function is related to an on angle, an off angle and a current overlap angle, the current overlap angle is generally defined as a constant by the traditional torque distribution function, but when the switched reluctance motor runs electrically, if the rotating speed of the motor or the load of the motor changes suddenly, phase current changes, so that the current overlap angle of two adjacent phases changes, and finally the torque changes according to an electromagnetic torque equation of the switched reluctance motor. Therefore, setting a constant overlap angle does not strictly guarantee that the sum of the distribution functions of the phases of the switched reluctance motor is always 1, resulting in that the resultant electromagnetic torque is not equal to the reference torque, thereby generating large torque ripple. The core of the direct instantaneous torque control of the switched reluctance motor lies in the design of a torque controller, the torque controller adopts a traditional hysteresis control method, the structure is simple, and the application effect of the hysteresis control method can be influenced by the setting size of the hysteresis limit. When the hysteresis limit range is set to be smaller, although the response speed of the system can be improved, the load of the power switching device is undoubtedly increased, and the power switching device can not respond under the condition of higher switching frequency, so that the serious consequence of system runaway can be caused; when the hysteresis limit is set to be larger, the control action of the system is weakened, the aim of inhibiting torque pulsation cannot be well achieved, and the power switch device of the system does not act in the hysteresis limit, so that the system enters a free response stage.
