Generalized projective synchronization of fractional-order complex networks with nonidentical nodes

doi:10.1088/1674-1056/21/12/120506

Abstract This paper investigates the synchronization problem of fractional-order complex networks with nonidentical nodes. The generalized projective synchronization criterion of fractional-order complex networks with order 0 < q < 1 is obtained based on the stability theory of the fractional-order system. The control method which combines active control with pinning control is then suggested to obtain the controllers. Furthermore, the adaptive strategy is applied to tune the control gains and coupling strength. Corresponding numerical simulations are performed to verify and illustrate the theoretical results.

Keywords: fractional-order complex networks generalized projective synchronization pinning control adaptive coupling law
