Abstract

Abstract: According to the current tracking of active power filter, a state feedback control strategy was applied to three-phase shunt hybrid active power filter system, replacing popular PID controller, to overcome the drawbacks of the PID controller, such as big overshoot, error compensation etc.. The mathematical model was established and the feedback control law was derived based on the topological structure of hybrid active power filter selected. Moreover, the current detection used i_p-i_q detection algorithm while the stability of capacitor voltage in DC side used PI control. MATLAB/Simulink was applied to simulate the HAPF system, comparing with the traditional PI hysteresis comparison control method. The results show that the state feedback control algorithm can obviously improve tracking performance of the system, and improve the harmonic compensation effect of APF.

Key words: active power filter, state feedback, current tracking control, harmonic compensation
