基于高效电压矢量选择的感应电机驱动占空比调制直接转矩控制策略

The traditional duty-modulated direct torque control (DDTC) suffers from the current distortion and the increased torque ripple due to the improper utilization of zero-voltage vector. To solve the above problems, a novel DDTC strategy based on efficient voltage vector selection is proposed for induction motor (IM). On the basis of analyzing the duty cycle of voltage vector and the droop characteri...
