A Numerical Algorithm for Chained Aggregation and Modified Chained Aggregation.

Abstract

A computer implementation of chained aggregation and modified chained aggregation using orthogonal transformations is presented. The numerical advantages associated with orthogonal matrices are highlighted. The developed algorithm is then employed to identify a reduced-order model of a large space structure. With the reduced-order model, an output feedback design is carried out. The design is shown to produce an acceptable result on the full order model. (Author)
