Torque ripple reduction in switched reluctance motor using a novel torque sharing function

A novel torque sharing function (TSF) to minimize the torque ripple of switched reluctance motor is proposed in this paper. Optimization criteria of a TSF that is concerned with an optimization problem including minimize copper loss and the maximum absolute value of the rate-of-change of the flux linkage (RCFL). In addition, a novel family of TSFs is proposed. An optimal TSF can be easily obtained from the family to satisfy the secondary objectives. The dynamic simulation model is built based on the Matlab/Simulink. The results show that the torque ripple can be minimized more obvious in high speed than that of low speed, demonstrating the effectiveness of the proposed control method.
