Abstract

This paper describes considerations for identifying models of large, lightly damped, flexible space structures to be used for high-performance control system design and analysis. The specific aspects of these problems are in turn used to derive a candidate system identification process for use on such systems. Particular attention is focused on two parts of this process, namely model order selection and model tuning. Three methods of model order selection are evaluated utilizing on-orbit data from the Satellite Ultraquiet Isolation Technologies Experiment (SUITE), which also provides a sample application for illustration of the proposed process.
