This paper proposes a novel resilient adaptive control scheme for controlling hypersonic flying vehicles under parametric uncertainties. First, a typically longitudinal dynamic model on a hypersonic flying vehicle was provided, and feedback linearization was implemented. The effect of parametric uncertainties on the linearized model was analyzed. On the basis of the abovementioned actions, the resilient adaptive control law was designed in two steps. A nominal controller was designed using the adaptive backstepping control scheme, and the constructed Lyapunov function was analyzed. The final controller was obtained, and the system stability was verified. Finally, a simulative experiment was carried out, and the results were compared with those of the standard backstepping control method. The proposed control method presented better adaptive ability for parametric uncertainties than the standard control method.
