Abstract
In this paper, the PID control analysis for active power filter (APF) is presented. Based on the analysis, it is clearly shown that a large overshoot and long setting time of DC bus voltage will occur when conventional PI controller is used in APF. To solve this problem, a novel control strategy is introduced to improve the performance of the controlled system. The stability of the closed-loop system will also be proved by using a Lyapunov function approach. At last, simulation results are given to verify the correctness of the PID analysis and illustrate the advantages of the control strategy for improving the compensation precision.
