Abstract: This paper presents a method for reduction of discrete interval systems using pole clustering and Padé approximation. For a given high-order system, denominator of the reduced-order model is obtained by pole clustering and the numerator is obtained by matching first r time moments of the system and its reduced-order model where r is the order of reduced-order model. Two numerical examples are included to illustrate the procedure.

Keywords: discrete interval systems; model reduction; Pade approximation; pole clustering; reduced order modelling.
