Abstract:

Three kinds of existing proportional + repetitive control composite control strategies for three-phase three wire active power filter are compared and analyzed,and two improved methods are proposed for the proportional + repetitive control in series composite control strategy,so that it has faster response speed and higher tracking accuracy than single repetitive control.The correctness and effectiveness of the control strategy are verified by theoretical analysis,MATLAB simulation and prototype test.

Key words: active power filter (APF), current loop control, proportional + repetitive control composite control, natural period delay
