Abstract
This paper proposes the design and analysis of repetitive control technique for tracking the output current of active filter. The Proportional plus Integral (PI) controller performs a feedback control task and the repetitive control law periodically adjusts the input command to the control system to achieve a desired trajectory. In this work, the repetitive control law is designed using optimization in the frequency domain. The method of finding minimum gains for the optimization cost function is also presented in this paper. Simulation results confirm here the performance of the proposed method. ฉ 2008 IEEE.
