Abstract
This note presents a method for the reduction of the order of interval system. The denominator of the reduced model is obtained by a direct truncation of the Routh table of the interval system. The numerator is obtained by matching the coefficients of power series expansions of t he interval system and its reduced model. A numerical example illustra tes the proposed procedure.
