In high‐power, high‐speed traction drive systems, the traction motor usually operates under one‐pulse PWM (pulse width modulation) mode (square wave) during high‐speed operation. The constant output voltage in this condition makes the traditional vector control inoperative anymore. In this paper, a modified vector control strategy using open‐loop current control instead of closed‐loop current control...
The performance of the induction machine driving system with indirect vector control can easily be influenced by the effects of parameter mismatch and eddy current, which result that the magnetizing component of stator current can't align with the rotor flux vector, especially in the range of high speed and flux weakening. In order to achieve accurate rotor flux orientation, a novel control strategy...
