Abstract :
In the d-q axes, the system of active and reactive current in the mathematical model of three-phase voltage-source PWM rectifiers is a highly coupled nonlinear system, which is difficult for control. This paper presents the control of current decoupling using input-output linearization method based on the model of PWM rectifiers. Moreover, the theoretical analysis and parameter setting algorithm are given in this paper. The control strategy is simulated by MATLAB and the results testifies that the method could realized decoupling control of three-phase PWM rectifiers, and shows the advantages of fast dynamic response and good robust quality.
