| 摘 要： | 仅在定子电流检测的条件下，通过引入辅助状态矢量的方法建立稳定的模型参考自适应观测器，以定子电流作为比较信号，辨识出转子电阻的同时，辨识出磁链和速率。文中分析了稳定的激励条件。仿真结果证明该方法的有效性。

| Abstract: | Under the condition that only stator currents are measureable,an adaptive observer of rotor flux and rotor speed are designed for an induction motor.This method is based on an auxiliary state and a stable adaptive observer of MRAS. As rotor speed and rotor resistance can be regarded as slowly varying unknown parameters,the stable excitation condition is proved satisfied and the estimated values converge to their true values.The simulation results verify the validity of this method. |
