摘　　要：介绍一种采用了模型参考自适应系统的速度估计方法的异步电动机无速度传感器矢量控制系统。利用MATLAB/simulink对该系统进行仿真,仿真结果表明该系统具有较好的动静态性能和较强的鲁棒性,同时能够获得与有速度传感器矢量控制相近似的控制效果。A kind of vector control system without speed sensor for asynchronous motor, in which the model reference adaptive system（MRAS） was used to estimate the rotor speed, was introduced. This system was simulated by means of MATLAB/Simulink, the simulation result showed that this system had better static and dynamic performance and stronger robustness, capable of possessing the similar control effect by vector control with a speed sensor.

关 键 词：矢量控制 无速度传感器 模型参考自适应系统
