This paper presents a new adaptive scheme for online estimation of stator resistance in speed-sensorless induction motor drives. The method is based on the adaptive control theory of model reference adaptive system (MRAS) approach with Luenberger observer. And the stability of the observer with stator resistance estimation in sensorless vector control of induction motors is proved by the Lyapunov's...
In sensorless vector control of induction motor using voltage-fed inverter, the flux estimation error caused by stator voltage error due to the dead time and switch voltage drop and so on can deteriorate the performance of vector control. This paper proposes a method to compensate the stator voltage error by utilizing the error value between the measured current and estimated current. The DC component...
