Relegation for Decentralized Control

Abstract

In this report, we describe the total effort at Ohio State on the Project Relegation for Decentralized Control. The first part of this reflects on one of the primary research topics which was considered in the first year of research. This work performed in the first year concentrated on optimal relegation. In the second part of the report, we concentrate on circuit analogies for large flexible space structures. Many large-scale systems such as flexible spacecraft appendages are nonlinear in behavior. But their large scale makes centralized control difficult. Thus, we propose several methods for designing decentralized control laws that take system nonlinearities into account. Equally important is the task of modeling large-scale systems. This motivated research on applying well-known circuit theory techniques to the problem of modeling flexible structures. The third part of this report describes work performed on another primary research topic which was considered in the first year of research-the use of singular perturbations for multi-time scale analysis of two-link structures. This work was developed for use in embedding active materials into the links and relegating the control tasks.
