  • Abstract This paper is concerned with the development of novel stability criteria for time-varying delayed systems. To this end, a new function which consisted of two quadratic functions with a special structural matrix is established to be a Lyapunov functional candidate. The proposed Lyapunov functional plays key role to decrease the conservatism of derived conditions which is verified by three numerical examples.
