Abstract :
Three degree-of-freedom model which describes the dynamics of unpowered gliding reentry vehicle is established. The output torques of RCS which described in body axis system and the control sequence of RCS are designed. Considering the station of low dynamic pressure, the hybrid control of reaction control system and aerodynamic control surfaces for gliding reentry vehicle was then designed. To solve the problem of control allocation, in the longitudinal control of vehicle, time-sharing control was adopted while hybrid control in the lateral control of vehicle. The simulation shows that the strategies and functions of control system are practical and the feasible of the hybrid control system.
