摘要
提出了一种永磁同步电动机转矩脉动抑制无位置传感器重复控制系统。速度环采用比例积分调节器与重复控制器串并联的复合控制结构,提高了速度环的跟踪性能,降低了系统因负载或其他扰动引起的转速波动;在扩展反电动势观测器中加入了电机扰动观测器和重复控制器,降低了因负载扰动和角度估计误差对电机稳定性的影响,抑制了转矩脉动。在MATLAB/Simulink仿真环境下进行了仿真,验证了该方法的有效性。
A repetitive control system of position sensorless was proposed for interior permanent magnet synchronous motors（ IPMSM） to suppress the torque ripple. The speed loop was composed with a composite control structure using the series- parallel connection of the repetitive controllers and PI controller for improving the tracking performance of the speed and reducing its fluctuations caused by the load or other disturbances. A motor disturbances observer and a repetitive controller were added in the extended back- EMF observer to reducing the influences by the load disturbances and the error of the angle estimations,therefore the torque ripple was suppressed. The simulation experiment was carried out in the Matlab /Simulink simulation environment and the effectiveness of this method was proved.
