Abstract

DC side voltage control is the key to the stability of active power filter (APF). In this paper the principle of APF DC side voltage power control is analyzed, type-2 fuzzy control strategy is proposed to the DC side voltage stability control, a type-2 fuzzy controller is designed to realize the dynamic regulation of the size and the fluctuation for the DC side voltage. Simulation and experimental results show that: the DC side voltage control of APF based on type-2 fuzzy controller has good dynamic performance and robustness, compared with the traditional PI controller, the type-2 fuzzy controller has less overshoot, faster response, stronger anti-disturbance and better control precision, it is more suitable to guarantee the stable operation of APF.
