New necessary and sufficient conditions for analyzing the strictly Hurwitz property of polynomials with perturbed coefficients are presented. Based on the minimax criterion, a simple and direct method is proposed to determine the maximal allowable open intervals for independently perturbed coefficients. The dependence of allowable coefficient perturbations on operating frequencies is also introduced.
