MOVER II - A Computer Program for Verifying Reduced-Order Models of Large Dynamic Systems

This paper introduces a computer code for model verification of linear dynamic systems. Presentation is made within the broader context of system identification, and the many alternatives available for implementing a code. Practical considerations of the system identification process are discussed first. Alternative methods are reviewed and a classification system for existing as well as nonexisting methods is proposed. Finally, a rationale for the selection of a particular modeling approach, type of measurement data, and estimation algorithm is discussed. Although MOVER II was not specifically designed for large space structures, its capabilities fulfill many of the needs now recognized as important in the verification of reduced-order models. Prior application involving extensive use of substructuring and coordinate reduction is discussed.
