This paper describes the design of a nonlinear robust adaptive controller for a flexible hypersonic vehicle model which is nonlinear, multivariable, and unstable, and includes uncertain parameters. Firstly, a control-oriented model is derived for con

A nonlinear robust control strategy for hypersonic vehicle in tracking the responses to a step change in altitude and airspeed is proposed. The vehicle model is nonlinear, multivariable, unstable, and includes uncertain parameters. Firstly, the analy
