A study of two-variable very strict Hurwitz polynomials with interval coefficients
P.K. Rajan, H.C. Reddy · 1991
The derivation of Kharitonov-type extremum polynomials for two-variable very strict Hurwitz interval polynomials using circuit theoretic techniques is presented. In this connection very strict reactance functions are defined and their properties studied. Applying the properties of two-variable very strict Hurwitz polynomials, extremum positive functions are identified to test interval positive functions belonging to the very strict category.>
