| 摘 要： | 通过多种无速度传感器研究方法的比较，对模型参考自适应方法进行了研究。该方法采用感应电压作状态变量，避免了积分引起的低频问题；同时采用在电压矢量方程两边都叉乘定子矢量电流的方法，显著降低了定子电阻参数变化（尤其是在低速时）的影响。最后给出了MATLAB仿真试验的结果。

| Abstract: | Based on model reference adaptive system （MRAS）, this paper presents a speed sensorless drive for induction motor. The induction voltage is used as the state variable to avoid the low frequency problem caused by the integral. The effects of the variations in stator resistance （particularly in the low speed） are significantly reduced by multiplying the stator current vector on the both sides of the voltage vector equation. Finally, we give the MATLAB simulation results. |
