Periodic synchronization of community networks with non-identical nodes uncertain parameters and adaptive coupling strength

doi:10.1088/1674-1056/23/3/030504

Abstract In this paper, we propose a novel approach for simultaneously identifying unknown parameters and synchronizing time-delayed complex community networks with nonidentical nodes. Based on the LaSalle’s invariance principle, a criterion is established by constructing an effective control identification scheme and adjusting automatically the adaptive coupling strength. The proposed control law is applied to a complex community network which is periodically synchronized with different chaotic states. Numerical simulations are conducted to demonstrate the feasibility of the proposed method.

Keywords: community networks periodic synchronization adaptive coupling strength uncertain parameters
