Study on speed sensorless for vector control system of induction motor

Yao Qing-mei

Abstract

A mathematic model of induction motor under two static framework is presented and a speed sensorless control method is proposed,which,according to vector control theory,and by the q-axis rotor flux converging on zero for speed identification,has replaced speed sensor.The validity of the model and feasibility of the speed control method are verified by simulation results.
