Generalized projective synchronization of two coupled complex networks of different sizes

摘要

We investigate a new generalized projective synchronization between two complex dynamical networks of different sizes.To the best of our knowledge,most of the current studies on projective synchronization have dealt with coupled networks of the same size.By generalized projective synchronization,we mean that the states of the nodes in each network can realize complete synchronization,and the states of a pair of nodes from both networks can achieve projective synchronization.Using the stability theory of the dynamical system,several sufficient conditions for guaranteeing the existence of the generalized projective synchronization under feedback control and adaptive control are obtained.As an example,we use Chua's circuits to demonstrate the effectiveness of our proposed approach.
