摘要：
A large variation in current will generated when using the traditional current hysteresis current control method, consequence, leading to torque ripples. In order to improve the current dynamic tracking ability and reduce the torque ripples, this paper proposed a novel method to enhanced tracking capability based on the torque distribution function strategy. The current tracking ability was improved without increasing the switching frequency or changing the hysteresis width. The PWM modulation mode such as "positive voltage-zero voltage" and "negative voltage-zero voltage" were selected flexibly to determine the freewheeling mode, demagnetization mode of the power converter. The simulation model and experimental platform of three-phase 12/8 pole switched reluctance motor were established. The simulation and experimental results verify the feasibility of proposed current control method in the torque ripple minimization by using linear torque distribution strategies. The saturation of the magnetic circuit are considered and the proposed approach is verified to be not affected when the motor operates under different load saturation condition. © 2019 Chin.
