摘　　要：首先介绍了有源电力滤波器在abc坐标系和dq坐标系下的数学模型,然后从自控原理的角度详细阐述了PI控制器作为有源电力滤波器的内环控制策略的不足,在此基础上,对PI控制器进行了改进,结合比例谐振控制器的基本原理,提出了一种新的控制策略,克服了传统PI不能很好地跟踪交流信号的缺点。仿真和实验结果证明了所提方法的正确性和有效性。First introduced the mathematical models of active power filter in abc coordinate system and dq coordinate system,then from the angle of the automatic control principle in detail elaborated the PI controller as theinner control strategy of active power filter,based on this,the PI controller was improved,in combination with thebasic principle of proportional resonant controller,a new control strategy was proposed,to overcome the traditional PIdefects which can not tracking AC signal well. Simulation and experimental results prove the correctness andeffectiveness of the method.
