This paper considers the issue of strongly robust stabilization of a set of linear, controllable, time-invariant and SISO systems of degree n 1. First of all the notion of Strong Robustness is introduced. Then we prove the existence of an open strongly robust spherical neighborhood around any system within the studied class. Next, balls of systems are considered and we give a sufficient and a necessary conditions on their radius to ensure their strong robustness. These results are illustrated by the example of first order pole placement design.
