摘　　要：针对矿井提升机对高性能调速的需要,对矢量控制技术进行了详细地研究,建立了基于模型参考自适应系统(MRAS)的无速度传感器异步电机矢量控制系统,实现了转速的在线辨识;又利用Matlab/Simulink对控制系统进行了建模仿真;仿真结果表明采用的控制策略控制效果良好,能在较大负载扰动下实现无传感器方式的异步电机的稳定运行。According to the need of high-performance speed control of mine hoist,the vector control technology is studied in detail.This paper establishes the speed sensorless vector control system of asynchronous motor based on the model reference adaptive system（MRAS）,and realizes the online identification of speed;And then this paper establishes the model of the control system in Matlab/Simulink;The simulation results show that the control strategy has good control effect and it can achieve the stable operation under perturbation of large load of asyn-chronous motor sensorless mode.
