Abstract
In this paper, a nonlinear indirect adaptive sensorless speed controller for induction motors is proposed. In the controller, only the stator currents are assumed to be measurable. Flux observers and rotor speed estimator are designed to relax the need of flux and speed measurement. Furthermore, two estimators are also designed to overcome the drifting problem of rotor resistance and unknown load torque
