Abstract :
In the present paper the problem of vibration suppression in segmented reflector telescopes is considered. The decomposition of the structure into smaller components is discussed and control laws for vibration suppression, as well as, conditions for stability at the local and global levels are presented. The states of the reflector segments are mapped into ray displacements on the detector plane.
