Abstract: This paper deals with the slewing maneuver of flexible space structures. The robust control rule is given for the linear systems with parameter uncertainty. The robust control is based on the Lyapunov' s theory of stability. Three kinds of control law are given in the forms of the linear control, nonlinear control with matching condition, and nonlinear control without matching condition, respectively. The robust control method is applied to the slewing maneuvers of Flexible Space Structures, and the simulation results prove that the robust control is effective for the Flexible Space Structures with parameter uncertainties.

Key words: Flexible Space Structures, Robust Control, Slewing Maneuvers
