An Improved Switching Table for PMSM DTC Drive Used in Electrical Vehicle

Abstract:

Article Preview

The DTC for PMSM possesses many advantages: simple control configuration, lesser parameters dependence and fast dynamic response and is a good choice for the drive of EV. But the DTC suffers from high torque ripples. The switching table is used as the hysteresis control rule that determines the control performance. An improved switching table is proposed based on effects of voltage vectors on the drive. Simulation results show this switching table can suppress torque ripple compared to the conventional switching table.
