Abstract :
A double-rate digital control law is proposed for large-angle attitude maneuvers and stabilization of flexible satellites. Such a control law improves, with respect to the continuous control, the damping of the elastic oscillations. Two sets of equations for modeling the spacecraft dynamics are given, an ideal one for simulation purposes and a simplified one for elaborating the control scheme. Simulation results illustrating two attitude maneuvers of a rigid body with four flexible attached booms, using gas-jet control, are discussed
