Model Predictive Control of Current Source Inverter for PMSM Drive

The main content of this paper is about the current source inverter device of permanent magnet synchronous motor (PMSM). Based on the method of finite-control-set model predictive control (FCS-MPC), a control strategy is proposed that can realize the torque and speed control of three-phase PMSM as long as the output capacitor voltage is controlled. Compared with the traditional control method, this method omits the adjustment of the weight coefficient and has better dynamic performance. In addition, the capacitor voltage control also has a good inhibitory effect on the resonance generated by the filter capacitor and the motor inductance. In this paper, the proposed control strategy is effectively verified by the simulation model.
