摘要
基于时域分析建立了三相三线有源电力滤波器(APF)电流控制回路的时域数学模型,研究了控制方程及其最优可行解。研究推导了电流控制回路滑模控制策略,提出了一种新的最优-滑模复合控制策略。该策略可以有效降低补偿电流跟踪误差,提高电流跟踪速度和精度,较好地抑制抖振现象,而且电流跟踪控制具有良好的鲁棒性和动态响应。算法还具有计算简单和易于应用的特点。仿真和实验结果证明了该控制策略的有效性和可行性。
A model of three-phase three-wire Active Power Filter （APF） current control loop is established based on the time-domain analysis, and control function and its optimal feasible solutions are studied. The sliding-mode control strategy of current control loop is deduced, and a novel optimization-sliding mode control strategy is proposed. The proposed strategy can reduce current tracking error effectively, suppress chattering better, improve current tracking speed and accuracy, and can provide both good robustness response and dynamic response of the current tracking control. It has the characteristics of simple computation and easy application. The simulation and experiment results show its validity and feasibility.
