| 摘 要： | 为了补偿控制延时对并联型有源电力滤波器常规PI控制的影响,提出了一种新型比例控制与重复控制相结合的延迟补偿控制方案。建立有源电力滤波器的离散解耦模型,指出延时使PI控制性能恶化,在此基础上引入重复控制补偿跟踪误差,保留PI控制中的比例环节使控制系统保持一定的快速性,通过详细分析确定复合控制系统的各种参数,使有源电力滤波器精确补偿非线性负载产生的谐波电流。应用Matlab进行仿真,结果表明,该方法使有源电力滤波器具有良好的稳态和暂态性能,验证了所提方法的正确性和有效性。

| Abstract: | In order to compensate the control delay of shunt active power filter(APF),a novel control strategy based on combination of proportional control and repetitive control is proposed.The discrete decoupling model of APF is established.The deterioration of PI control arise from control delay is indicated by analysis.Then repetitive control is adoptedto compensate tracking errors,and proportional portion of PI control is preserved to maintain rapidity.A variety of parameters of the combined control system are determined through detailed analysis.Simulations are performed by Matlab,the results show that the proposed method has well steady and dynamic characteristics,which verifies its feasibility and validity. |
