Adaptation-Based Reconfiguration in the Presence of Actuator Faults with Non-Measurable Rates

In this paper, a direct adaptive control reconfiguration is proposed for flight control with actuator faults characterized by second-order dynamics. Under non-measurable rates, adaptive state feedback control scheme is developed, which ensures that all closed-loop signals are bounded and plant tracking error tends to zero asymptotically, despite the uncertainties in actuator faults and plant parameters. The properties of the proposed algorithms are evaluated through numerical simulations of an aircraft example.
