In this paper, the application of adaptive control is demonstrated for highly flexible aircraft in a dynamic gain scheduling approach. For that, an adaptive control law is designed for the stability augmentation system, taking as reference model the closed-loop dynamics provided by a baseline controller. Global stability is demonstrated by the Lyapunov direct method. Closed-loop nonlinear simulations are performed. The performance of the control system is evaluated considering the aircraft in high loading operations, specifically in accelerated turning maneuvers. Overall, this control strategy proved to overcome instabilities arising when linear control is applied, while conferring the aircraft adequate time response.
