Summary:The main objective of this contribution is to present the application of a graphical approach to robust stability analysis of discrete-time uncertain polynomials with special emphasis to polynomials with a complicated nonlinear uncertainty structure. The generalization of the value set concept and the zero exclusion condition under robust D-stability framework is used for this purpose. The relative simplicity of the applied technique is shown by means of the illustrative examples. Keywords: Robust stability; discrete-time polynomial; parametric uncertainty; nonlinear uncertainty structure; value set; zero exclusion condition.
