Robust Stabilization of Large Space Structures with Rigid Interconnections

Abstract

This paper presents a robust stabilization of large space structures with rigid interconnections. It is shown that direct velocity and displacement feedback or simple dynamic displacement feedback can robustly stabilize the structures against any purturbations in mass, damping, and stiffness. Furthermore, the stability of the overall system is preserved even if the controller of a subsystem fails. These facts mean that these control laws have the same ability about robust stability and fault tolerance.
