| Abstract: | A nonlinear mathematical model of three-phase voltage source PWM rectifier was established in the rotating frame dq. By applying the nonlinear feedback theory, the corresponding nonlinear coordinates change matrix was deduced, and an accurate state-feedback linearization model of the rectifier was derived, thus proposing a decoupled control strategy between the reactive and active powers. Simulation results show that, by using the proposed control strategy, the decoupled control of three-phase voltage source PWM rectifier can be perfectly realized, and the rectifier is of excellent dynamic characteristics. |
