摘　　要：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。Aim to metro application, without speed sensor control algorithm based on model reference adaptive system （MRAS） was introduced in detail, and the methods of the stator resistance identification to improve the accuracy of speed estimation in very low-speed region was proposed to meet metro large torque startup requirement. The control algorithm was validated that could implement full-condition speed estimation by ground and on-board test, and completely satisfied all requirements of metro applications. Its successfully application in Wuxi metro line-1 also showed that the system was reliable.
