基于模糊控制的有源滤波器直流母线电压控制

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

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。

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 over- shoot over traditional DC voltage control methods.
