Study on the Speed Identification of the Speed sensorless Vector Control System of Induction Motors

提出一种新型的异步电机转速辨识方案。根据异步电机的数学模型，利用易于检测的电机定子电压和电流得到电机转速的模型参考自适应辨识算法。通过对无速度传感器矢量控制系统的仿真，结果证明该方案具有较好的辨识精度。

A novel approach to estimate induction motor speed is presented in this paper. According to the reduced order model of induction motor, a model reference adaptive speed identification algorithm is obtained from measured motor stator voltages and currents. Computer simulation results show that better performance of proposed model in terms of accuracy can be achieved with the approach.
