In this study, the H-infinity tracking control problem of a linearized hypersonic vehicle model with the bounded external disturbance is investigated. Firstly, the nonlinear longitudinal dynamics of hypersonic vehicle is linearized as a linear time-invariant system with the bounded external disturbance, a reference model is introduced for the aim of tracking control. And then an observer-based output feedback tracking controller design approach is proposed by using the linear matrix inequalities (LMIs) technique. The asymptotical stability of the closed-loop system is analyzed in the framework of Lyapunov method. Finally, the simulation results are given to illustrate the applicability of the developed control approach.
