OPUS: Optimal Projection for Uncertain Systems

Abstract

OPUS: Optimal Projection for Uncertain Systems is a unified approach to control-system design and analysis for high-performance, multivariable applications such as large flexible space structures. In particular, OPUS yields low-order, robust controllers which meet both time- and frequency-domain objectives. The present report is divided into three main research areas: (1) Fixed-Structure Design, (2) Robust Analysis and Design, (3) Further Extensions. Major accomplishments of the research program include: (1) A unified approach to reduced-order, robust modeling, estimation, and control including singular problems and decentralized architectures, (2) A computationally tractable approach to designing low-order, finite-dimensional controllers for distributed parameters systems, (3) A thorough development of quadratic Lyapunov bounds for robust stability and performance analysis, (4) Complete unification of L2 (time- domain) and H at infinity (frequency-domain) design criteria for full- and reduced-order modeling, estimation, and control.
