    A kind of Terminal sliding mode controlling method is proposed for hypersonic vehicle with modeling uncertainties and external disturbance.Based on hypersonic vehicle pitch channel control system,a new integral type Terminal sliding mode is put forward.By introducing the first order filter and combined with Backstepping method,the singularity problem is eliminated.The compensation of controller performance is realized by means of the disturbance observer.The stability of the system is proved with Lyapunov theory to ensure the improvement of the dynamic performance of the system.The performances and robustness are analyzed through hypersonic flight simulations.The simulation results show that: 1)The disturbance observer can follow the tracks of the disturbance rapidly;and 2)The Terminal sliding mode controlling method can guarantee the stability and high control precision under the conditions of nominal parameter and large-scale parameter perturbation.
