摘　　要：以单相并联有源电力滤波器(SAPF)为研究对象,针对直流侧电压影响在传统PI控制方面存在的超调量静差较大,影响APF补偿性能问题,提出了模糊自适应PI控制策略。在传统PI控制和模糊控制理论基础上,设计了一种模糊自适应PI控制器。仿真结果表明,该控制策略较传统PI控制策略响应速度更快、超调量更小,而且提高了直流侧电压的稳定性及APF的补偿性能。Taking single-phase shunt active power filter(SAPF)as the research object,aiming at the problem that the DC side voltage has a large overshoot static error in the traditional PI control and affects the compensation performance of APF,a fuzzy adaptive PI control strategy is proposed.Based on the traditional PI control and fuzzy control theory,a fuzzy adaptive PI controller is designed.The simulation results show that the control strategy has faster response speed and smaller overshoot than the traditional PI control strategy,and improves the stability of the DC side voltage and the compensation performance of APF.
