摘　　要：由无源滤波器和有源滤波器串联构成的并联型混合有源滤波器适用于高压大容量的谐波补偿场合。将重复控制引入并联型混合有源滤波器。先简单地介绍了并联型混合有源滤波器的基本工作原理,并对其进行建模,在此基础上将重复控制应用于有源滤波器部分输出电压的控制,以提高其跟踪精度,进而改善混合有源滤波器的谐波补偿效果。结合系统的模型,给出了其重复控制器设计和稳定性分析的方法。最后通过MATLAB仿真研究,验证了该控制策略可以有效提高稳态补偿精度,同时具有良好的动态性能。SHAPF（Shunt Hybrid Active Power Filter）,which combines PPF（Passive Power Filter） and APF（Active Power Filter） in series,is suitable for the harmonic compensation in large-capacity and high-voltage situations.A high-performance control strategy based on repetitive control is introduced to SHAPF.The basic working principle of SHAPF is briefly explained and its model is established.The repetitive control is applied in APF output voltage control to improve its tracking accuracy,as well as the harmonic compensation effect of SHAPF.The design method of repetitive control and its stability analysis are given based on the SHAPF model.MATLAB simulation study shows that,with excellent dynamic performance,the control strategy improves the steady-state compensation accuracy effectively.
