# Speed sensorless field oriented control of induction motor with rotor resistance adaptation

@article{Kubota1993SpeedSF, title={Speed sensorless field oriented control of induction motor with rotor resistance adaptation}, author={Hisao Kubota and Kouki Matsuse}, journal={Conference Record of the 1993 IEEE Industry Applications Conference Twenty-Eighth IAS Annual Meeting}, year={1993}, pages={414-418 vol.1} }

The authors present a method for estimating simultaneously the motor speed and the rotor resistance of an induction motor by superimposing AC components on the field current command. In addition, a rotor resistance adaptive scheme is proposed in order to decouple the rotor resistance adaptation with the motor speed variation. The validity of the proposed method has been verified by simulation.<<ETX>>
