摘要：

The application of switched reluctance motors (SRMs) is greatly restricted by the torque ripple issue caused by its doubly salient structure and nonlinear electromagnetic characteristics. This paper presents a torque sharing function control based on online torque compensation in commutation region.The commutation region is divided into two regions by the torque current ratio at low-speed and the torque flux rato at medium-high-speed. Meanwhile, in order to deal with the negative torque caused by the tail current of the previous phase, an adaptive commutation control strategy is proposed, where the phase current and motor speed are related to the commutation angle. The delay or the advance commutation angle can be calculated to select the optimal commutation angle. In order to verify the efectivenes of the method, simulations and experiments are carried out in this paper. It is proved that the scheme can effectively reduce the torque ripple of the SRM. © 2022 Editorial Department of Electric Machines and Control. All rights reserved.
