Modified function projective lag synchronization of uncertain complex networks with time-varying coupling strength

Abstract

In this article, we investigate the issue on modified function projective lag synchronization (MFPLS) of dynamical complex networks with disturbance and unknown parameters, the dynamical network is a complex network model containing uncertainty and coupling delay, the coupling strength is time-varying in the complex networks. Theoretical analysis and numerical simulations about MFPLS of uncertain complex networks are presented, not only unknown parameters of the networks are estimated, but also unknown bounded disturbances can be simultaneously conquered by adaptive laws and adaptive coupling strength obtained from Lyapunov stability theory.
