Traditional model predictive control(MPC) is highly dependent on model and has poor robustness. Aiming at these problems, self-correction model predictive control is proposed in this paper. According to the model of three-phase voltage source PWM rectifier, the predictive current can be calculated and the actual model parameters can be estimated by the actual current. The proposed algorithm is practical in correcting model parameters, eliminating the effect of model parameters mismatch on the system and improving the robustness of the control system. Simulation and experimental results show that the presented self-correction model predictive control method has better robustness and excellent control performance.
