Aimed at that longitudinal hypersonic vehicle model has some features such as high nonlinearity, multivariable coupling and parameter uncertainty, etc., a new dynamic surface sliding mode control scheme for hypersonic aircraft based on nonlinear disturbance observer is proposed. In the scheme nonlinear disturbance observer is used for observing the unknown nonlinear disturbance and the observer is in exponential convergence by selecting the design parameters, then the dynamic surface sliding mode control is designed, and the proposed control scheme can be adopted to guarantee the semiconsistent and stable global system. Simulation results demonstrate that the use of the proposed control scheme can effectively overcome the nonlinear disturbance and enhance the robust performance of the system
