Robust stability of quasipolynomials Vertex-type tests and extensions
Résumé
In this paper we study the robust stability of uncertain quasipolynomials, whose coef£cients may vary in a certain prescribed range. We consider speci£cally the co-called interval and diamond quasipolynomials, and our goal is to develop vertex- and edge type-conditions for these quasipolynomial families to be robustly stable independent of delay. Moreover, we also present a number of extensions to more general uncertain quasipolynomials, including both frequency-sweeping and vertex/edge type results.
