Adaptive backstepping control of induction motor with uncertainties

Adaptive backstepping control design is applied to a nonlinear induction motor system model with both electrical and mechanical dynamics. To emphasize the motion control applications, the effective inertia and load torque are considered as unknown parameters. With full state measurement, both rotor speed and rotor flux amplitude tracking objectives are satisfied, which improves power efficiency without affecting the speed regulation. The proposed approach has a straightforward design and stability analysis procedure, while avoiding overparameterization and keeping the control law structure simple
