摘 要: 基于对三相三线有源电力滤波器电流控制方程的时域分析,得出了滑模变结构控制的一般控制律。该方法具有跟踪的快速性好、计算量少、适合于有源电力滤波器的实时控制等优点。给出了三相三线制有源电力滤波器仿真结果,结果证明了该文方法的正确性和可行性。 Based on the time-domain analysis on three -phase three-wire active power filter current control loop, the common sliding-mode control strategy of current control - loop is deduced. The control performance is analyzed, the proposed control strategy can provide a good dynamic response of the current tracking control, and reduce chattering, and has the characteristics of simple computation and easy application. Simulation results show its validity and feasibility.
