摘　　要：针对传统有源滤波器无功和谐波复杂的检波单元,以及为克服系统负载切换时对直流侧电容电压的影响,提出了电源电流直接控制的有源滤波器,省去了传统有源滤波器的谐波检测单元,介绍了电源电流直接控制的有源滤波器的基本原理,并且直流侧电容电压采用PI和自适应模糊PI两种控制方式,在Matlab/Simulink环境下对两种控制方式在系统响应时间,超调量以及负载扰动情况下进行仿真,并且对两种仿真结果进行了比较.仿真表明采用自适应模糊控制的算法,系统的响应速度加快,调节精度提高,稳态性能变好,而且没有超调和振荡,具有较强的鲁棒性.In view of traditional complex harmonics and reactive power,detecting part,and also the effect on the dc-link voltage when the system is switching the load,this paper proposes the filter that saves traditional detecting part of filter.This kind of filter is directly controlled by source current.The paper also introduces the basic principle of the APF controlled by source current.Dc-link voltage applies two controlling method which contains PI and adaptive fuzzy PI.The simulation results are compared in Matlab/Simulink environment on three sides,which are system response time,overshoot and load disturbance.The simulating result indicates that accelerating the system response speed load,improving the accuracy of regulation and bettering the steady state.None overshoot and oscillation,stronger robustness are the advantages of applying adaptive fuzzy controlling algorithm.
