摘　　要：分析了三相三线制有源滤波器的工作原理.针对重复控制动态响应慢的特点,提出了重复控制加单周期控制的复合控制策略.利用重复控制提高了系统的稳态精度,单周期控制提高了系统的动态响应.基于MATLAB/Simulink软件对该控制方法进行了仿真,仿真和实验结果表明:该复合控制方法可以使系统具有良好的稳态补偿性能和动态响应速度,证明了该方法的有效性.The operating principle of three-phase three-wire active power filter was analyzed.Aiming at the slow dynamic response performance of repetitive control,a compound control strategy based on repetitive control and one cycle control was proposed.The repetitive control was used to improve the system control static precision and the one cycle control was used to improve the dynamic response performance.The system model was built and simulated based on MATLAB/Simulink.The results of simulation and experiment show that compound control can make system have characteristics of good static compensation performance and quick dynamic response performance,and the results verify the validity of the compound control.
