This paper focuses on the tracking problem for airbreathing hypersonic vehicles, and proposes a new control method on the basis of not canceling, but using, aeropropulsive, as well as elevator-to-lift, couplings to design controllers without strategically avoiding or reducing the nonminimum-phase characteristic. The controllers and the external reference trajectories are simultaneously obtained by solving a system of linear algebraic equations. The altitude error is shown to be asymptotically stable. The velocity, flight-path angle, angle-of-attack, and pitch-rate errors all exponentially converge to zero with the proposed tracking controllers. The suppression of the flexible dynamics is achieved by integrating the new control method with control. To enhance the robustness of the controllers with respect to the uncertainties of the aerodynamic parameters, a nonlinear disturbance observer is proposed to estimate the variations of the aerodynamic parameters for airbreathing hypersonic vehicles during cruise flight.
