Abstract :
Continuity/discontinuity of robustness indicators is reviewed. For the case of real or mixed uncertainty, a regularization of a conservative bound to the robustness margin is proposed, and its properties are discussed. In the case of polynomial families with affine dependency on the uncertainty, a regularization of the robustness margin results
