Abstract:There are overshoot control and the existence of static error larger issues in the traditional PI DC voltage control of the Shunt Active Power Filter (SAPF). In this paper, fuzzy internal model control is used in the the DC capacitor voltage control of the three-phase three-wire SAPF, The method is based on DC capacitor voltage changes, and the initial value parameters of internal model control is automatically adjustd by the fuzzy control rules so that at any time the most appropriate internal model control parameters could be used. Compared with the traditional DC voltage control, the method improves the stability of the DC side voltage control, effectively inhibites the overshoot and reduces the static error. Simulation results are presented to indicate the validity of the proposed algorithm.
