As the flight scale of Near-Space Vehicle(NSV) is extremely large,especially the velocity is hypersonic,the system must have strong nonlinearity,coupling and fast time-variability and be influenced by strong disturbance and uncertainty.It is a big challenge for the control system.Therefore,Sliding Mode Disturbance Observer(SMDO) based Nonlinear Generalized Predictive Control(NGPC) strategy which combines the robust of Sliding Mode Control and the upstanding dynamic character of Predictive Control together is raised and the control law is designed for the hypersonic NSV attitude control system.Simulation result shows that this flight control system has nicer control characters and high disturbance repellence.
