The decentralized robust servomechanism problem with constant disturbances/set points is considered in this paper for large flexible space structures (LFSS). It is shown that for LFSS which have colocated, mutually dual sensors and actuators, the decentralized fixed modes of the system are precisely equal to the centralized fixed modes of the system. Simple necessary and sufficient conditions are then obtained for a solution to exist for the robust decentralized servomechanism problem for the system. A controller is demonstrated which, for this class of LFSS systems, eliminates the 'spillover problem'. A two-hundreth-order numerical example of an LFSS control problem using the Purdue model is included to illustrate the results.
