针对无速度传感器控制技术在地铁中的应用问题,详细介绍了基于模型参考自适应的无速度传感器控制算法,同时采用定子电阻辨识的方法提升了极低速工况下的速度辨识的精度,满足了地铁大转矩启动的要求。通过地面试验和装车试验充分证明了该算法能实现全工况下的速度辨识,完全满足地铁各种工况的运行要求,在无锡地铁1号上的长时间载客运营表明了控制系统的可靠性。
Aiming at the application of speed sensorless control technology in metro, the speed sensorless control algorithm based on model reference adaptive is introduced in detail. At the same time, the method of stator resistance identification is used to improve the speed identification accuracy at very low speed, Metro torque starting requirements. Through the ground test and loading test, it is proved that the algorithm can realize the speed identification under all working conditions and fully meet the operation requirements of various working conditions of the subway. The long-term passenger operation at Wuxi Metro No.1 shows that the control system reliability.
