电流跟踪控制是并联型有源电力滤波器(APF)的控制器设计的关键问题之一,利用APF的无源特性来实现电流跟踪控制可以取得较常规的线性和非线性控制器更好的控制效果。首先建立了三相四线制下四桥臂APF的状态空间模型;在此基础上利用无源控制方法构造电流跟踪动态控制器,然后基于APF的工作机理分析给出了实现渐近跟踪和内部稳定的充分条件;最后利用 PSCAD软件包对所提出的控制算法进行了仿真测试,证明了新算法的有效性。
Current tracking control is one of the key issues in the controller design of shunt active power filter (APF). The use of passive characteristics of APF to achieve current tracking control can achieve better control than the conventional linear and nonlinear controllers effect. Firstly, the state space model of four-leg APF under three-phase and four-wire system is established. Based on this, the current tracking dynamic controller is constructed by passive control method. Then, based on APF working mechanism analysis, the realization of asymptotic tracking and internal The stability of the sufficient conditions; Finally, the use of PSCAD software package for the proposed control algorithm simulation test to prove the effectiveness of the new algorithm.
