摘　　要：在传统的基于PI控制的有源电力滤波器直流侧电压控制方法的基础上,提出了模糊自适应控制的直流侧母线电压控制新方法。通过模糊控制规则,可以自动调整PI参数,从而提高了系统的动态响应,消除了系统的稳态误差。仿真结果表明:该方法响应快、无超调、鲁棒性强,较传统PI控制具有更好的动、静态特性。On the basis of PI control method for active power filter DC-side voltage,a novel control method was brought forward, which was self- adaptive fuzzy PI control. According to the fuzzy control rule, this strategy could change PI parameter automatically, improve the dynamic response of the system,and reduce the error of the stable state. The simulation results indicate that the fuzzy self-adapting PI controller method is superior to the traditional PI controller in that the former works well with high dynamic and static performance because of its advantages in quick response and good robustness.
