TL;DR: In this article, a control-oriented model in closed form is obtained by replacing complex force and moment functions with curve-fitted approximations, neglecting certain weak couplings, and neglecting slower portions of the system dynamics.

TL;DR: In this article, a nonlinear, physics-based model of the longitudinal dynamics for an air-breathing hypersonic vehicle is developed, which captures a number of complex interactions between the propulsion system, aerodynamics, and structural dynamics.

TL;DR: In this article, a nonlinear robust adaptive controller for a flexible air-breathing hypersonic vehicle model is proposed, where a combination of nonlinear sequential loop closure and adaptive dynamic inversion is adopted for the design of a dynamic statefeedback controller that provides stable tracking of the velocity and altitude reference trajectories and imposes a desired set point for the angle of attack.

TL;DR: In this paper, a robust output-feedback control for a model of an airbreathing hypersonic vehicle is presented and evaluated by means of simulations of a full nonlinear model of the vehicle dynamics and is tested on a given range of operating conditions.

TL;DR: In this paper, a non-linear, physics-based model of the longitudinal dynamics for an air-breathing hypersonic vehicle is developed, which captures the complex interactions between the propulsion system, aerodynamics, and structural dynamics.
