摘　　要：针对有源电力滤波器(APF)投入电网启动时存在冲击电流和冲击电压的问题,在直流侧电容电压比例积分(PI)控制方法的基础上,设计了一种专家PI控制器来控制APF直流侧电容电压的启动过程。从受控对象和基于经验知识的专家控制理论出发,结合PI控制建立整个电路模型。在Matlab/Simulink中进行了仿真验证,并将该方法在60 kVA实验样机上进行了测试。通过与常规PI控制对比证明该方法具有超调量小、动态性能好、稳态误差小的优点,并且在工程上有良好的应用价值。The rushing current and voltage are occuring when the active power filter （APF） is started into the grid.An expert proportional-integral（PI） controller is designed to control the starting process of APF DC side capacitor voltage based on DC side capacitor voltage PI control method.Based on the controlled object and expert control theory,the entire circuit model is established which combined with PI control.This method is simulated in Matlab/Simulink and tested in 60 kVA experimental prototype.The method has little overshoot, good dynamic performance, little steady-state error by contrast with the conventional PI control method and has excellent application value in engineering.
