摘　　要：针对由电流谐波导致转矩脉动而影响电机性能的问题,课题组建立了谐波转矩模型,同时基于三相瞬时无功功率理论结合PI控制搭建了谐波抑制模块,并以谐波电流环的方式并入控制系统实现抑制电流谐波和降低转矩脉动的目的。仿真结果表明:将谐波抑制模块加入到永磁同步电机矢量控制系统后,永磁同步电机定子端相电流波形的正弦度提高,各次谐波失真率均有所降低,转矩脉动受到抑制。该研究为永磁同步电机的转矩脉动抑制提供了一种有效方法。Aiming at the problom of torque ripple caused by current harmonics affecting motor performance,a harmonic torque model was established.Simultaneously,a harmonic suppression module integrated into the control system through a harmonic current loop was built based on the theory of three-phase instantaneous reactive power combined with a PI controller,and the purpose of suppressing current harmonics and reducing torque ripple were achieved.The simulation results show that when the harmonic suppression module is added to the PMSM vector control system,the sinusoidal degree of the stator phase current waveform is increased,the content of each harmonic is reduced,and the torque ripple is suppressed.It can provide some guidance for PMSM torque ripple suppression.
