Stable Simultaneous Stator and Rotor Resistances Identification for Speed Sensorless IM Drives: Review and New Results

After a technical review on the stator resistance and rotor resistance identification methods for speed sensorless induction motor drives, this paper presents a different solution with a new representation of induction motor dynamics. By virtue of this representation, an adaptive observer is designed. The key step is to introduce the corrective terms and the filtered regressors, which forces the e...
