CONTROL-STRUCTURE INTERACTION STUDY OF THE PROPOSED SPACE STATION FREEDOM

A relatively general formulation for studying the dynamics and control of an arbitrary spacecraft with interconnected flexible bodies has be en developed accounting for transient system properties, shift in the center of mass, shear deformations, rotary inertias and geometric nonl inearities. This self-contained, comprehensive, numerical algorithm us ing system modes is applicable to a large class of spacecraft configur ations of contemporary and future interests. Here, versatility of the approach is demonstrated through the dynamics and control studies aime d at the evolving Space Station Freedom.
