In this paper, the problem of robust matrix root-clustering is addressed. The studied matrices are subject to both polytopic and unstructured uncertainties. An original point is the large choice of clustering regions enabled by the proposed approach since these regions can be unions of possibly disjoint and nonsymmetric subregions of the complex plane. The precise purpose is, considering a specified polytope, to determine the greatest robustness bound on the unstructured uncertainty such that robust matrix root-clustering is ensured. To reduce conservatism in the derivation of the bound, the reasoning relies on a framework based upon parameter-dependent Lyapunov functions. The bound value is computed by solving an L M J problem.
