摘要：

Aiming at the torque ripple problem of doubly salient electro-magnetic motor (DSEM) during operation, this paper proposes a nine-state torque closed-loop control strategy. On the basis of the actual nonlinear inductance model, the control strategy performs state switching at the zero-crossing point of the back electromotive force of the motor to suppress commutation torque ripple caused by current freewheeling. In addition, a traditional two-phase conduction mode is inserted near the negative zero-crossing point of each back EMF to increase the motor output. This paper analyzes the change characteristics of the phase current and torque output of the DSEM in each mode, and demonstrates the feasibility of the proposed control strategy based on the duty cycle analysis. Meanwhile, the influence of the commutation angle on the control strategy is summarized. Finally, through experiment, this paper verifies that the proposed control strategy can effectively suppress the motor torque ripple and has great dynamic performance and high torque-ampere ratio. ©2023 Chin.Soc.for Elec.Eng. 6441.
