Abstract:A new double closed loop control strategy of three-phase voltage-sourced PWM rectifier based on IMC,which is composed of inner current loop and outer voltage loop.Based on a decoupling control with IMC,the inner current loop can obtain the decoupling of active current and reactive current.Based on the idea of power conservation and disturbance-rejection control with two-degrees-of-freedom IMC,the outer voltage loop can not only realize the linearization control of voltage loop,but also,simultaneously,achieve characteristics of fast-tracking and excellent disturbance-rejection of the DC voltage.The simulation results demonstrate the validity and the feasibility of the proposed new control strategy.
