This paper considers an induction motor model controlled by stator currents in the presence of unknown resistance, inductance, and load torque. A parameter-linearized regression model is derived from the control-signal dynamics, enabling the application of the Dynamic Regressor Extension and Mixing (DREM) technique. Using measurements of the rotor angular velocity, an estimation algorithm for the unknown parameters and a rotor-flux observer are developed. The proposed dynamic control law stabilizes the motor at a constant reference speed and guarantees global stability of the closed-loop system.
