OPUS: Optimal Projection for Uncertain Systems.

Abstract

Increased interest in deploying large flexible spacecraft has focussed attention on active structural control techniques to achieve crucial advances in vibration suppression, pointing accuracy and shape control. The extreme complexity of such systems and the lack of accurate finite-element structural models present severe control design challenges which were extensively accumulated by previous Government research Programs. OPUS is a rigorous new approach to this class of problems, which embodies a fundamental generalization of classical steady state linear quadratic Gaussian (LQG) optimal control theory. The present scope of the theory includes robust, reduced order modelling, estimation and control for continuous-time, discrete-time and sample data systems. Keywords: Optimal Control; Parameter uncertainty; Robustness; Reduced order dynamic compensation.
