基于模糊控制的有源滤波器直流母线电压控制

针对传统直流侧电压控制方法存在超调量和静差较大的问题,设计了混合有源电力滤波器控制系统,建立了混合有源电力滤波器的系统模型,并针对直流侧电压控制设计了一套双模糊控制器,与传统直流侧电压控制方法相比,该控制方法具有超调小、响应速度快、静差较小的特点。仿真结果验证了该方法的正确性和可行性。

Hybrid Active Power Filter DC Bus Control Based on Dual Fuzzy Control

In view of the existing problems of overshoot and static error of DC bus voltage control methods,a design of hybrid active power filter control system is presented in this paper.In the system,a hybrid active power filter system model is established.In order to control DC bus voltage,a double fuzzy controller is designed as well.The Matlab simulation results show that the system has the advantage of faster response,smaller static error and overshoot over traditional DC voltage control methods.
