| Abstract: | In order to improve the performance of permanent magnet synchronous traction motor (PMSTM) in electric vehicle (EV) drive, a novel direct torque control (DTC) strategy is proposed. Based on the operating mode of PMSTM, zero voltage vectors are chosen to obtain quick dynamic torque response and reduce inverter switching loss. An optimization control method about stator flux linkage is presented to improve system efficiency, the core of which is the real-time regulation of stator flux linkage by measuring inverter input power. Simulation and experimental results prove the proposed strategy. |
