摘要

A nonlinear mathematical model of three-phase voltage source PWM rectifier is established in the dq rotating frame. Aiming at the poor dynamic performance of conventional PI controlled three-phase PWM rectifier, a control system with double close-loops of voltage and current is designed based on the mathematical model of 3-phase PWM rectifier. A sliding-mode control algorithm on synchronous rotating reference frame for the out-voltage-loop is proposed. Then, a decoupled state-feedback control method is applied to the current loop. The whole system is modelled and simulated between the proposed method and conventional double PI control. The results show that the proposed controller confers faster dynamic performance and robust performance.
