【Abstract】 In order to reduce the steady state error and improve the dynamic response of the control system. This paper analyzes the advantages and disadvantages of the traditional PI controller and repetitive control in current loop control of the shunt active power filter.Through comparative analysis,proposing combining with PI regulator and repetitive control together named composite control. Theoretical analysis and simulation results demonstrate the feasibility of this view.更多还原
