| 摘 要： | 为了提高并联型有源电力滤波器（ APF）的补偿性能,在同步旋转坐标系下提出了一种理想的电流控制策略,即基于数字PI控制和重复控制并联结构的复合电流控制方法。利用重复控制对于周期扰动信号无差跟踪的特点来提高有源滤波的稳态精度,PI控制保证APF的动态性能。试验结果和理论分析结果表明,并联结构的补偿电流控制器是可行的。

| Abstract: | The advanced repetitive controller in parallel was used to eliminate the steady current tracking error caused by cyclic disturbance signal to improve the compensation precision of active power filter （ APF ） , while the ordinary PI controller was used to ensure the dynamic response performance of APF. The theoretic analysis and experimental results show the feasibility of the output current controller architecture is verified completely. |
