摘要

In this paper, we introduce a new notion of stability for nonlinear time-varying systems called \(h^*\) h -stability which represents a generalization of existing works in the literature. The main purpose of this new notion is to investigate the global uniform \(h^*\) h -stability of a class of time-varying systems using Lyapunov method that involves indefinite derivatives. Moreover, we provide illustrative examples to showcase the application and effectiveness of our proposed approach.
