摘　　要：为提高有源电力滤波器补偿的灵活性和补偿精度,提出了一种以传统PI为内环,重复控制为外环的双环复合电流控制器。给出了设计方法和动态性能、稳态性能分析。并提出了将基于多同步旋转坐标的指定次谐波提取与双环复合控制相结合实现无静差指定次谐波补偿的复合控制策略。仿真和实验结果证明了研究内容的有效性和正确性。To improve the flexibility and the precision of compensation of three-phase shunt active power filter, a double-loop compound current controller was proposed, which repetitive controller as the outer loop, the PI controller as the inner loop. Design method in detail, dynamic response and steady-state characteristic in analysis. And put forward the compound control strategy, which combine selective harmonic detection based on multiple synchronous rotating coordinates with double-loop compound controller, achieved the compensation of zero steady-state error and selective harmonic current. Both simulation and experimental results verify the effectiveness and correctness of the content.
