Abstract：In order to explore the three-level PWM rectifier high-performance control method when inductor and equivalent resistance parameters mismatch, a novel multi-model predictive control strategy is proposed combining multi-model adaptive control with model predictive control. In this control strategy a multi-model control system is designed for the three-phase PWM rectifier based on the parameter measurements and range of disturbance. Several sub-models are selected by judging the deviation between each sub-model predicted output and actual output. The optimal system parameters are determined through a weighted sum. To solve online computational burden caused by the combination of multi-model adaptive control and model predictive control, comme a simplified algorithm is designed by optimizing the moving subset and designing multi-level fast predictive control method. The experimental results demonstrate the validity of the proposed method and the feasibility of the control strategy.
