Abstract :
This paper discusses the problem of the stability bounds for structured parameter uncertainties of continuous-time linear systems. An improved condition is obtained which provides a robust stability criterion based on both the eigenstructure of the original system and the structure of the expected uncertainties. As examined by the illustrative examples this condition enhances the interval of the permissible uncertainties which do not affect the stability of the system.
