Abstract

An alternative approach for robust stability analysis of uncertain systems modelled in state-spaceis suggested.A new candidate for Lyapunov function and based on it stability condition which generalizemost of the available results in the field are presented.The applicability of this approach is illustratedby an example, treated many times by different approaches.
