Switched reluctance motor drive system has greatly practical value in electric vehicle applications. For the characteristics of switched reluctance motor and electric vehicle application requirements, how to reduce the torque ripple effectively and ensure its average output torque, all these become a hot spot of research. Based on this, first of all, the nonlinear model of switched reluctance motor is established and then the function relation between optimal turn-off angle and rotational speed is established based on the dynamic model simulation data, in the end, the optimization torque controller is designed successfully based on variable turn-off angle strategies. The simulation results show that the optimization torque controller can effectively restrain the torque ripple and improve its average torque and realize the torque dynamic characteristics optimization of switch reluctance motor, all these advantages meet the operation performance requirements of electric vehicle.
