The main objective of this paper is to design a dynamic surface adaptive fuzzy controller for a three-phase active power filter (APF). In order to deal with the nonlinearity of the APF, a fuzzy strategy combining an adaptive backstepping method is proposed where fuzzy controller is mainly responsible for the elimination of nonlinearities. Moreover, by adopting the dynamic surface method, the number of input variables of the fuzzy system in modeling could be reduced; therefore, the controller and design parameters can be implemented without complex calculation. The Lyapunov stability of closed-loop system with the fuzzy control, sliding control, and dynamic surface control could be assured. The simulation results prove that the dynamic surface adaptive fuzzy method has excellent performance in stability, robustness, adaptability, and total harmonic distortion (THD), which is confirmed to suppress harmonics effectively.
