Abstract :
This paper deals with the control of an axisymmetric moving mass actuated reentry vehicle. Three channel stable dynamic equations of the reentry vehicle are obtained derived from Newtonian theory. Since the maneuvering flighting in the reentry stage is mainly in the longitudinal plane, linear equations of the vehicle in the longitudinal plane based on linear perturbation theory are available. In addition, the control system of the moving mass actuated reentry vehicle is designed based on variable structure control method. Results obtained from simulations indicate the nonlinear model satisfy performance index demands of the attitude control.
