In traditional model predictive control(MPC),non-parameter model based on pulse response is usually adopted as predictive control model,which results in complex computation,so this method is difficult to be applied to real-time control system directly.An improved MPC method was presented and applied to power factor correction system of current source PWM rectifiers(PWM-CSR).In the proposed MPC,the first-order differential equations were derived from the transfer functions of controlling variables and contro...
