摘　　要：针对永磁同步电机定子电流畸变使电机电磁转矩脉动的问题,分析了电磁转矩脉动的主要原因,在建立永磁同步电机谐波模型的基础上,提出总谐波电流提取的方法,并通过谐波电压注入的方法来抑制定子电流中的谐波分量.在Simulink下建立传统控制仿真系统及加入总谐波电流抑制的仿真系统,对比分析各系统的方针结果,验证了该方法的理论可行性.In order to solve the motor electromagnetic torque pulsation problem that cause by permanent magnet synchronous motor stator current distortion. This paper analyzes the main reasons of the electromagnetic torque rip- pie, establishment of the harmonic model of the permanent magnet synchronous motor（ PMSM）, on the basis of es- tablishing the harmonic model of the permanent magnet synchronous motor. This paper proposes the methods of ex- tracting total harmonic current, and by the methods of harmonic voltage injection to suppress the harmonic compo- nent of stator current. In combination with the total harmonic current suppression and traditional control simulation system in the Simulink simulation system, comparison and analysis of the principle of the system, the theoretical feasibility of the method was verified.
