Model order reduction of discrete time uncertain system

Abstract

This article represents a new and combined technique for finding single-input-single-output (SISO) model with interval system in reduced form using modified Routh approximation (RA) and matching of Time moments (TM) and Markov parameters (MP) of reduced order models and higher order interval system. This aimed methodology is illustrated with the help of one test system. The system responses validate the superiority of the proposed technique.
