Maximum Entropy/Optimal Projection Design Synthesis for Decentralized Control of Large Space Structures

Abstract

The Maximum Entropy/Optimal Projection (MEOP) Methodology is a novel approach to designing implementable vibration-suppression controllers for large space systems. Two issues, in particular, have been addressed, namely, controller order (i.e., complexity) and system robustness (i.e., sensitivity to plant variations). Extensions developed herein include generalizations to decentralized controller architectures and a new robustness analysis technique known as Majorant Robustness Analysis. This final report also encompasses extensions to hierarchical control as well as the development of numerical algorithms for solving the control design equations. Keywords include: Robust control design, Decentralized controller, and majorant robustness analysis.
