Abstract

A new state-space model for flexible satellite is set up. This paper focuses on the satellite system subjected to modal frequency uncertainty. The uncertainty is nonlinear, and a function of disturbance parameters. This kind of disturbance´s upper bound and robust control for this class of uncertain systems are studied. Finally, by simulation experiment, it is shown that the method in this paper has reached the desired target. The uncertain satellite system has good robustness for modal frequency uncertainty.
