Active power filter (APF) is an effective means to control the harmonic pollution of the power grid. Repetitive control is widely used in APF for it can track the reference signal periodically without error. The dynamic response of traditional repetitive control is slow for it has a periodic delay of fundamental wave. So it can’t track instruction current in time and has a bad effect. This paper introduce the improvement of repetitive control which can achieve better compensation effect from different aspects. A brief comment on the desirability and deficiency of various methods is given. Finally, the existing problems of the improved repetitive control are explained.
