摘要
该文研究了带有模糊逻辑控制器和积分比例器的有源功率滤波器电路,分析了该电路的控制特征,通过模糊逻辑算法和数值模拟,结果表明:该控制电路具有良好的控制功能和输出电流的追踪能力。
A three-phase active power filter（APF） operating with fixed switching frequency and controlled by a fuzzy logic controller in the inner current control loop for each phase and a proportional-integral（PI） controller in the outer voltage control loop is studied. The performance and characteristics of active power filter circuit are analyzed. Using the fuzzy logic algorithm and Metlab simulation, the results are found that the tracking capability of the APF output current and the controlled performance of the power circuit are unsurpassed.
