摘要

This paper presented a novel space vector pulse width modulation (SVPWM) control based on exact feedback linearization. A affine nonlinear model of three-phase shunt active power filter (APF) was built. The nonlinear state feedback control law is derived to accomplish the linearization of APF model and to realize decouple control of active and reactive compensation currents. The command voltage can be exactly obtained which should be output from AC side of APF by selecting appropriate feedback coefficients. The command voltage is approached using SVPWM method. Simulation was carried out to verify the validity and advantage of the proposed control method, which compare with triangle wave modulation method based on PI controller. A small experimental prototype was designed to verify the correctness and feasibility of proposed control method.
