| 中文摘要: |
| 针对储纬器电机无位置传感器的调速控制问题，采用脉振高频注入法与扩展反电动势法相结合的控制策略，研究了一种全速域下的无位置传感器矢量控制方法。在电机静止时，利用电机凸极特性，采用高频注入法配合极性判断准确估计初始位置并使电机速度闭环启动。当运行至中速时，估计算法切换为扩展反电动势法估计转子位置与速度。在加减速过程速度切换区间采用滞环切换策略。通过实验验证了所提出的控制策略在全速域下电机矢量控制的可行性，且满足储纬器电机配合织机的工作要求。 |

| In order to solve the sensorless velocity control problem of weft feeder motor, a sensorless vector control method in full speed range is proposed, which adopts the control strategy of combining pulse vibration of high frequency injection method with extended back electromotive force method. When the motor is stationary, the high-frequency injection method and polarity judgment method are used to accurately estimate the initial position and start the motor speed in closed loop. When running to medium speed, the estimation algorithm is switched to the extended back electromotive force method to estimate the rotor position and speed. Hysteresis switching strategy is adopted in the speed switching interval during acceleration and deceleration. The feasibility of the motor vector control in the full speed range is verified by experiments, and it meets the working requirements of the weft feeder motor cooperating with the loom. |
