Current source inverters can tolerate short circuits, which can reinforce the reliability of system when it drives the PMSM. This paper presents a sequential model predictive control of current source inverter for PMSM drive system. This method based on the model predictive control, using cost functions of the output capacitance voltage, the torque, d-axis current, and the switching frequency respectively. This control method has the advantages of small computation and fast dynamic characteristics, and it doesn’t need weighting factor. Establishing the simulation model of the current source inverter of PMSM, the results prove the effectiveness of the control scheme.
