Title

Multivariable Routh-approximant Model Reduction Method in the Time Domain

Abstract

The time-domain Routh-approximant method for model reduction of large-scale systems is modified and enhanced in this paper. a new transformation matrix that overcomes a limitation of earlier work is proposed. This feature greatly enhances the multivariable method. Some interesting results on symmetry properties are developed in conjunction with a structure example. a sufficiency condition of stability of the reduced-order model is identified. the response of the reduced-order model traces the original system very well. Thus the Routh method offers promise for application in the suboptimal control of large space structures, given its inherent simplicity.
