摘　　要：根据直接转矩控制系统的直接控制转矩思想,通过对传统直接转矩控制策略的扇区进行重新划分改进,并在此基础上对扇区进行细分,得到改进的开关电压选择表。在Maltab/Simulink中,得到定子磁链轨迹、转矩响应、定子电流等结果,仿真结果表明转矩和定子电流脉动有较大降低,定子磁链轨迹建立速度有较大的提高。According to the torque control directly ideal of the direct torque control system, the modified voltage vector switching table was obtained through the redistricting of the conventional direct torque sector and the subdividing of the redistricted sector. The results of stator flux trajectory, torque response and stator current were obtained through Matlab/Simulink. The results show that the torque and stator current ripple are reduced obviously, and the establishing speed of the trajectory of stator flux is enhanced.
