有源电力滤波器作为解决电能质量问题的重要手段，在电力系统中发挥着越来越重要的作用.提出了一种用于有源电力滤波器电流控制的非线性重复控制器。所提出的方法是由一个重复控制器和死区继电器。当输入误差超过阈值时，电流控制环由死区继电器控制，以获得快速的动态响应。在输入误差低于阈值之后，死区继电器自动关断，并且重复控制单独支配电流控制以消除稳态误差。文中还对电流和电压控制回路的设计进行了讨论。仿真和实验结果验证了该方法的可行性。
Active power filters as solutions to power quality problems have become more and more important nowadays. A nonlinear repetitive controller for current control of active power filters is proposed. The proposed method is composed of a repetitive controller and a deadband relay. Whenever the input error is above the threshold, the current control loop is driven dominantly by the deadband relay to obtain fast dynamic response. After the input error is below the threshold, the deadband relay automatically turns off and the repetitive control alone governs the current control to eliminate the steady-state error. Discussions on the design of the current and voltage control loops are also given. Simulation and experimental results verified the feasibility of the proposed method.
