This paper describes an advanced control method of induction motors using an improved Integral-Backstepping version. The application of the conventional version of this technique has proven that it can cause bad behaviour during certain operating conditions because of its structure based on the integral action, which can cause strong vibrations accompanied by overcurrent before the final system stabilization. The adjustment presented in this work to improve the control and ensure its stability in the different operating zones is to incorporate the variable gains structure in the speed regulator. This modification generates a command composed of two distinct parts: the first guarantees optimal control around the equilibrium point by using high gains to ensure robustness in front of external disturbances. The second part is intended for transient regimes; it is characterized by relatively small gains with a total absence of the integral action to guarantee good convergence stability. The determination of each control law will be carried out based on Lyapunov’s theorem, and the experimental validation will be performed using a dSAPCE-DS-1104 card. The experiments conducted show a high-efficiency real-time control with an interesting improvement in terms of robustness, stability, and good speed tracking capacity.
