Abstract：As for model current predictive control, the output current of all switch states is needed to be predicted and evaluated in each sampling period. It requires complex calculation and high-performance controller. A model voltage predictive control algorithm is proposed in this paper and used for the control of three-phase voltage source rectifier (VSR). Based on the inverse process of the model current prediction, the reference voltage can be calculated. The vector plane is then divided into seven sections and the corresponding section of the reference voltage is determined, according to which the optimal voltage vector is obtained and utilized as the controller output. The proposed method does not require loop optimization and the prediction time is short. Also, the control method is simple and easy to be implemented. Experiments are conducted to analyze the presented model voltage predictive control algorithm. The results show that the proposed algorithm has excellent static/dynamic state performances and obviously reduces the calculation time of the model predictive control.
