Periodic resetting-MRAC in control of a high-speed aircraft

This paper is concerned with the application of a modified model reference adaptive control (MRAC) algorithm on a real system. The proposed scheme introduces the concept of periodic resetting of adaptation mechanism (PRAM). The algorithm developed has been applied to the longitudinal control problem of a high-speed fighter aircraft. Simulation results proved that the proposed technique is capable to alleviate the stability problems of the available standard MRAC-algorithms, in the presence of unmodeled dynamics and sinusoidal disturbances
