DTC-SVM of five-phase permanent magnet synchronous motor drive

In this paper, a direct toque control (DTC) and space vector modulation (SVM) are combined to control a five-phase permanent magnet synchronous motor drive (PMSM). Based on the mathematical model of five-phase motor, DTC control strategy is developed, and the corresponding controllers are properly designed in order to provide independent torque control. Five-phase SVM is adopted, instead of look-up table, to improve the overall performance of multiphase drive. The efficacy of the proposed method is verified by simulation at various dynamic operating conditions.
