Abstract :
The problem of controlling the induction motor pi- model with magnetic saturation is considered, speed sensorless adaptive controller is developed under the assumption of measurable electrical states but unknown rotor resistance, and load torque. All the unknown parameters are assumed constant or slowly varying and are estimated online by the controller. Simulation results are provided for illustration.
