摘要：
In order to solve the frequent problem of breaking shaft in the starter/generator system of switched reluctance motor, a novel Direct Instantaneous Torque Control (DITC) is proposed to control the torque ripple in this paper. Instead of the hysteresis controller in traditional DITC, the PWM is introduced to modulate the torque deviation; the optimal switching signal is selected according to the PWM modulation signal and the sector where the rotor position is located. Based on the torque characteristic curves, the torque ripple during commutation period is analyzed and the compensation methods are proposed. Simulation results prove that the compensated PWM-DITC can suppress the torque ripple of switched reluctance motor effectively.
