Abstract
Coefficients of characteristic polynomials for parametrically uncertain systems are allowed to perturb to some extent. Stability radius is a useful tool to analyze the stability for the systems. To enhance its usefulness, we modify stability radius so that it takes into account of given restricted perturbations, which we call directional stability radius. For an application, we show shifted-Hurwitz stability conditions and an analysis method for interval polynomial systems using the directional stability radii.
