Abstract :
In this paper, an adaptive fuzzy control system with supervisory controller is proposed to improve dynamic performance of three-phase active power filter (APF). The proposed adaptive fuzzy controller for APF does not need to establish accurate mathematical model and has the ability to approximate the nonlinear characteristics of APF. The adaptive law based on the Lyapunov analysis can adaptively adjust the fuzzy rules, therefore the asymptotical stability of the adaptive fuzzy control system can be guaranteed. Simulation results show that this control method has an excellent dynamic performance such as small current tracking error, reduced total harmonic distortion (THD), strong robustness in the presence of parameters variation..
