Model predictive torque control for PMSM with duty ratio optimization

This paper presents the application of model based predictive torque control (MPTC) with duty ratio optimization for permanent magnet synchronous motor (PMSM) drives. By using MPTC, significant reduction in torque and flux ripples can be achieved by selecting the voltage vector best satisfying the demands of torque and flux. Moreover, the MPTC drive system can maintain the performance by incorporating duty ratio optimization of the active vector with a lower sampling frequency. Simulation results are presented to demonstrate the effectiveness of the proposed schemes in this paper.
