    Abstract:

    Switched reluctance motor (SRM) had the characteristics of torque ripple. A direct instantaneous torque control strategy combining hysteresis control and pulse width modulation (PWM) was proposed. Based on the analyses on the mechanism of large fluctuations in torque during control process, different control methods were formulated for singlephase and commutation zones. Considering the output characteristics of torque under different conditions, the PWM equivalent strategy was introduced into the hysteresis limit interval to optimize the torque control effect. Fuzzy adaptive PID controller was added to improve the response performance of the system. The simulation results showed that the control strategy had a fast response and could suppress the torque ripple of the SRM effectively.
