双凸极电磁电机转矩脉动抑制的虚拟磁场定向控制

This article proposes a virtual field-oriented control to reduce the torque ripple and improve the torque–ampere ratio of doubly salient electromagnetic machine (DSEM). Since the DSEM adopts stator excitation and the rotor only provides a magnetic circuit, the traditional rotor field-oriented control cannot be directly applied to the DSEM. At the same time, it is challenging to establish the rotor...
