MPC-SVPWM based controller for PMSM drives [articol]

Abstract

In this paper, a model predictive control based drive for the permanent magnet synchronous motor is proposed. This proposed method is suggested to achieve high dynamic torque in the PMSM. The control variable’s long run behavior is predicted by the MPC within the time domain of the control system and the selection of the optimization cost function. This method combines the advantages of the MPC and SVPWM technique for PMSM drive to overcome the variations in the electromagnetic variables and also supplies fixed frequency for the inverter. The effectives of the proposed method is analysed and demonstrated in the simulations. The experimental set up is done with a frequency inverter that controls the PMSM motor. The dead time for the inverter is fixed to prevent a shoot-through fault. The experimental results are presented which shows the PMSM performance.
