Reconfiguration of fixed-wing UAV control system in autonomous flight

A reconfiguration method using model-based control allocation scheme is proposed in this paper. A reconfigurable closed-loop control system is established for control of a UAV (unmanned aerial vehicle) fixed wing aircraft in autonomous flight in case of single and multiple control surfaces failures. The control allocation is determined by using of a nonlinear dynamic model of a UAV aircraft. The model is also used to demonstrate the proposed method. Simulation results show that the damaged aircraft control via proposed reconfiguration method can be carried out and satisfactory controllability performance may be achieved.
