This paper has proposed an efficient direct torque control strategy based on space vector modulation (SVM-DTC) for dual three-phase permanent magnet synchronous motor (DTP-PMSM), which is implemented in a synchronous reference frame aligned with the machine stator flux vector. This strategy adopts the space vector modulation technique to compensate for the stator flux error, and then the continuous smooth response of the vector control and the rapid response of direct torque control are both achieved. Simulation studies of a 3KW DTP-PMSM are carried out. Simulation results show the improvement of the torque response, decrease of the torque ripple, the higher steady performance and better flux waveform.
