An Identification Procedure For The Tuning Of A Robust Fractional Controller

An identification procedure for the tuning of a robust fractional controller is proposed in the paper. The fractional controller is a time delay fractional PID controller, adapted to a large class of systems, and insuring robustness to static gain variations. The identification procedure, based on the Output Error algorithm, permits to define a worst case model, used to tune the fractional controller, in order to provide robustness to identification uncertainties. Numerical experiments illustrate the different steps of this tuning procedure.
