摘　　要：本文首先分析了混合型有源电力滤波器的结构及工作原理,针对传统电流跟踪控制方法响应速度慢、稳定性能差的缺点,本文采用了基于递推积分的Pl控制算法,并且取得了比较好地控制效果,另外,针对该控制算法响应速度比较慢的问题,本文采用了一种模糊算法在线调整递推积分PI的系数,以此提高其响应速度,仿真结果证实了该控制算法可以改善APF系统的动态跟踪性能和稳态性能。As the traditional current tracking control method has the defects of slow response and poor stability, this paper used P1 control algorithm based on recursive integral, and achieved good control effect, in addition, due to the problem of slow response of the control algorithm, this paper proposed the coefficient of a fuzzy algorithm adjusting on-line recursive integral PI, in order to improve the response speed, simulation results showed that the control algorithm can improve the dynamic tracking performance and steady-state performance of APF system.
