The current tracking control strategy determines the compensation performance of shunt active power filter (SAPF). Due to\ninadequate compensation of the main harmonic by traditional proportional integral (PI) control, a control algorithm based on PI\nand multi vector resonant (VR) controllers is proposed to control SAPF. The mathematical model of SAPF is built, and basic\nprinciple of VR controller is introduced. Under the synchronous reference frame, the proposed control method based on pole zero\ncancellation is designed, which narrows the order of the control system and improves the system dynamic response and the\ncontrol accuracy. Then the feasibility of the method is demonstrated by analyzing the closed loop frequency characteristics of the\nsystem. Finally, the simulation and experimental results are carried out to verify the performance of the proposed method.
