Aiming at the problems of overshoot and static error in the shunt active power filter (SAPF) direct current side voltage control, a new control strategy based on linear active disturbance rejection control(LADRC) is proposed. Its mathematical model is established by SAPF structural analysis, and then a second-order expanded state observer is designed and the error feedback unit is linearized. Linear active disturbance rejection controller applied to APF direct current side voltage control. The simulation results show that the application of linear active disturbance rejection control can effectively improve the compensation performance and dynamic response speed of SAPF compared with traditional PI control strategies, which verifies the effectiveness of the control method.
