Abstract :
Based on results of A.V. Lipatov and N.I. Sokolov (1979) simple sufficient conditions for the robust stability of both (strictly) Hurwitz and Schur interval polynomials are obtained. Furthermore, sufficient conditions are derived for robustness of (strictly) Hurwitz and Schur polynomials whose coefficients of linear functions of a single parameter. Several examples are discussed illustrating the derived results.<>
