有源电力滤波器要求补偿的电流具有很好的实时性,自适应PID控制技术能在线调整参数满足实时控制的要求。文章就并联电压型有源电力滤波器中实际补偿电流对谐波电流的实时跟踪技术,采用自适应模糊PID控制进行研究,整定得到最优PI参数,最后将自适应模糊PI控制器应用于仿真电路。仿真结果验证了此控制器的正确性和有效性。
Active power filter current compensation requirements have good real-time, adaptive PID control technology can adjust parameters online to meet the requirements of real-time control. In this paper, real-time tracking of actual compensation current and harmonic current in parallel voltage-type active power filter is studied by using adaptive fuzzy PID control, and the optimal PI parameters are set and adjusted. Finally, the adaptive fuzzy PI controller is applied to the simulation Circuit. Simulation results verify the correctness and effectiveness of this controller.
