An Optimal Design of PI Control in the Application of Active Power Filter

Abstract:

This paper mainly introduces an optimal design of PI control based on compensation to eliminating the interference and improving the performance of the system. With the mathematic model of shunt APF in d-p rotating coordinate, simulation indicates that there is a period disturbing signal in the current closed loop of shunt APF based on the conventional PI control, which obviously impacts on the current tracking performance of the system. So a new PI control based on compensation is put forward. Through the simulation in the platform of Matlab/Simulink, it turns out that this method can improve the current tracking performance of APF and stable performance of the system.
