Global Chaos Synchronization of Chen and Cai Systems by Active Nonlinear Control

Dr.V. Sundarapandian, R. Karthikeyan


In this paper, we study the global chaos synchronization of identical Chen systems (1999), identical Cai systems (2007) and non-identical Chen and Cai systems. In this paper, active nonlinear control has been deployed for the synchronization of identical and non-identical Chen and Cai systems and synchronization results are proved using Lyapunov stability theory. Since the Lyapunov exponents are not required for these calculations, the active nonlinear control method is very effective and convenient to synchronize Chen and Cai systems. Numerical simulations are also given to illustrate the effectiveness of the synchronization schemes proposed in this paper for Chen and Cai systems.
