Abstract

The unified power quality conditioner (UPQC) has the function of voltage-current compensation devices. To enhance its comprehensive compensation effect, this paper combines the traditional PID regulator and fuzzy control theory and designs a fuzzy-PID controller to apply in UPQC DC-link capacitor voltage control links and tracking control link of the compensation. The method synthetizes the strong advantages of the high accuracy of traditional PID control steady-state and robustness of the fuzzy control. The simulation results in Matlab/Simulink environment show that the control rules can effectively improve the performance of compensation.
