A mutual model reference adaptive method for the rotor speed and stator resistance identification is proposed in this paper to implement a speed sensorless direct torque control of induction motors.

本文介绍了一种可互换模型参考自适应方法实现对电机转速和定子电阻的辨识，并将其应用于异步机的无速度传感器直接转矩控制中。

Stator resistance and pure integration are removed from the reference model, resulting in robust performance in wide speed range.

参考模型中不含定子电阻，并且避免了纯积分运算，因而在宽速度范围内具有较好的鲁棒性。

Reference source and sample resistance are all thermostatic.

基准源及采样电阻均采用恒温措施。
