A robust controller based on backstepping design procedure is proposed for an air-breathing hypersonic vehicle with aerodynamic
propulsion and structural couplings. Expressing the control system as strict feedback form via the curve-fitted model
virtual and actual controllers are constructed for the velocity and altitude subsystems. To omit analytic calculation of the virtual control law derivatives
which is very difficult to evaluate in the traditional backstepping control
robust differentiators are introduced. Super-twisting sliding mode disturbance observers are designed to compensate uncertainties in the system dynamics. Trajectory tracking simulation performed on the first principle model of the vehicle's longitudinal dynamics shows that the designed controllers are robust to model fitting errors and outside disturbances
and the system states reach trimmed condition asymptotically.
