摘　　要：由于传统比例积分(PI)控制无法实现零稳态误差控制,设计了一种基于比例复数积分控制的有源电力滤波器,该控制器在给定次谐波处具有无穷大增益,可以使某些特定次待补偿谐波实现零稳态误差控制,并且不需要解耦控制,简化了控制器的设计。结合带宽的定义,给出了控制器参数设计方法。通过理论分析和仿真研究对分别采用PI和比例复数积分控制的APF的补偿特性进行了比较研究,验证了通过并联比例复数积分控制器在APF应用上的有效性。Traditional PI controller can＇t obtain zero steady-state error, so active power filter based on proportional complex integral control is designed, which has infinite gain at the given harmonics, can make some given compensation harmonic achieve zero steady-state error control, do not need decoupled control, and simplifies the controller design procedure. According to the definition of bandwidth, the parameters design method is given for this controller. Comparison of the performance of active power filter based on PI controller and proportional complex integral control is conducted through theoretical analysis and simulation, and the validity is verified for application of parallel proportional complex integral in active power filter.
