Torque ripple minimization for switched reluctance motor with predictive current control method

In order to reduce the torque ripple and improve the torque-speed characteristic of switched reluctance motor, a novel predictive current control method is proposed in this paper. Compared with conventional current hysteresis control, the current tracing ability is improved by using proposed method without increasing switch frequency or changing hysteresis band. Both of torque ripples and copper loss reduction of different TSFs are investigated respectively. Experiments with 5.5kw three-phase 12/8 SRM verify the effectiveness of the proposed control strategies.
