双凸极永磁电机新型控制策略研究

Study on New Control Strategy for Doubly Salient Permanent Magnet Motor

在对双凸极永磁电机数学模型和静态参数分析的基础上,该文分析了其转矩脉动的产生原因。针对常规转速电流双闭环控制策略转矩脉动大的缺点,提出了一种新型转速转矩电流三闭环控制策略。基于Matlab/Simulink搭建了电机和控制器模型,仿真结果表明了控制策略的正确性和有效性。

Based on the analysis of the mathematic model and static parameters of the doubly salient permanent magnet（DSPM） motor,the torque ripple was analyzed.The traditional control strategy with speed and current loops suffers from severe torque ripples,hence a novel control strategy with speed-torque-current loops was proposed.DSPM motor and controller were modeled in Matlab/Simulink,and the simulation results were given to verify the proposed approach.
