摘　　要：以单相并联有源电力滤波器(APF)为研究对象,针对直流侧电容电压影响APF补偿性能的问题,提出了将下垂控制和模糊自适应比例积分(PI)控制相结合的下垂模糊自适应PI控制方法。首先,分析模糊自适应PI控制的工作原理;再针对传统直流侧电容电压控制存在补偿开关器件损耗与补偿性能的不足,提出采用下垂控制器获得直流侧电容电压控制的参考值,并对下垂控制与模糊自适应PI控制相结合的控制方法进行了理论分析;最后,对提出的方法进行了Matlab/Simulink仿真和实验验证。结果表明:相对于模糊自适应PI控制方法,提出的控制方法响应速度更快、超调量更小,且提高了直流侧电容电压控制的稳定性及APF的补偿性能。Based on single-phase shunt active power fiher（APF） as the research, aiming at the problem of DC-side capacitor voltage influence the compensation performance of APF, the control strategy of the combination of droop control and adaptive fuzzy proportional integral（P I） control is put forward.Firstly,the fuzzy adaptive PI control principle is analyzed,and then for the insufficient compensation switching device loss and compensation performance existence in conventional DC-side capacitor voltage control, droop controller is proposed to obtain the DC-side capacitor voltage control with reference value, and theoretical analysis and the fuzzy adaptive PI control combined control method, finaly the Matlab/Simulink simulation and experiment are carried out.The results compared to fuzzy adaptive PI control show that the proposed control strategy has fast response and small overshoot, even improves the stability of DC-side capac- itor voltage control and 1he compensation performance of APF.
