Robust Decentralized Control
Abstract
This report considers the problem of designing decentralized control systems for Large Space Structures to satisfy robustness and performance requirements for multiple system configurations. The problem is motivated by the fact that such structures will have to be assembled in space. A partially assembled structure will need some real-time control so that it maintains its' station, performs partial functions, and damps oscillations during assembly. Completely reprogramming the control computers each time a subassembly is incorporated in the structure is likely to be impractical. A more sound engineering approach would be to require the same control system design to satisfy performance requirements for the partial assemblies and to maintain stability for the completely assembled structure. Performance can then be restored for the full assembly by applying an outer loop (hierarchical) control or adjusting the decentralized design parameters.
