Abstract

Given a strictly Hurwitz polynomial , it is of interest to know how much the coefficients aican be perturbed while simultaneously preserving the strict Hurwitz property. For systems with , maximal intervals of the aiare given in a recent paper by Guiver and Bose [1]. In this note, a theorem of Kharitonov is exploited to obtain a general result for polynomials of any degree.
