Abstract

Many methods of rotor resistance identification have been presented in the study of an induction motor speed sensorless system. In this paper, a novel method of rotor resistance identification in the steady state based on torque disturbance injection is proposed. Digital simulation and experiment results show the precision of the identification and the good performance of the system in the no-load and full-load condition.
