誘導電動機の速度センサレスベクトル制御における回生運転の高トルク制御法

抄録

We developed a torque stabilization method for the regenerative operation of speed sensorless vector controlled induction motor (IM) drives. Speed sensorless vector control suffers from a torque reduction phenomenon in regenerative operation. Therefore, we analyzed the cause and developed two stabilization methods: one to stabilize the decrease in IM flux and the other to adjust the velocity command in the low-speed range. Time domain simulations and experiments demonstrate the effectiveness of the proposed method.
