基于DSP的矢量控制系统中感应电机参数自检测方法研究

DSP based Identification of Induction Motor Parameters in Sensorless Vector Controlled system

无速度传感器矢量控制的系统中,参数的检测精度很大程度上决定系统的控制精度。文章从异步电机的数学模型出发,从电路分析的角度提出了一种简单易行的参数辨识算法,实践结果表明它能为无速度传感器矢量控制系统提供较高精度的电机参数。

In a senseless vector control system, The precision of motor parameter determine the precision of the whole control system. According to the mathemati cal model of the induction motor and in an electrocircuit analysis point of vie w, a new practical method has been achieved. The realization result indicates th at this method can offer quite accurate electrical parameter for senseless vecto r control system.
