Résumé :	This work presents new ideas to improve adaptive control schemes by introducing fractional calculus elements. Many adaptive concepts are studied, and new control algorithms are proposed using fractional order operators (differentiator, integrator) as well as fractional order transfer functions. The state of the art of fractional order control systems is presented with definitions of the most important notions of fractional calculus. And the different approaches of adaptive control concerned with this work are introduced together with the classical control algorithms. The main contribution of this work is to propose many fractional adaptive control schemes, mainly : – Model reference adaptive control with control rules using fractional order integration or the process output derivative of fractional order with a fractional order reference model. – Fractional order high-gain adaptive control where the gain depends on a norm fractional integral of the process output. – PIλDµ adaptive control using fractional order integral and derivative, this control scheme being inspired from the high-gain control. By comparing these results with classical integer order control schemes, we show an important performance improvement (response time, settling time, stability) and a better robustness against noises and perturbations. These observations are illustrated by numerical simulations and theoretical arguments in the case of high-gain adaptive control.
