摘要：

Due to the comparatively serious torque ripple problem of doubly salient electro-magnetic motor (DSEM), a method of torque closed-loop control is proposed to suppress the torque ripple. Firstly, under the process of commutation of DSEM, the current variation characteristics of each phase in different conduction modes which have influence on torque output are analyzed. Secondly, on this basis, owing to fully utilize the torque output capacity of each phase, an electric cycle is divided into different sectors in which the state of the switches for the control strategy is defined. Finally, the simulation results on a 12/8-pole DSEM validate the proposed strategy which can restrain the torque ripple and improve the output capability of torque.
