Global Chaos Synchronization of T and Cai Systems by Nonlinear Control

This paper investigates the global exponential synchronization of chaotic systems, viz. identical T systems (Tigan and Opris, 2008), identical Cai systems (Cai and Tan, 2007) and synchronization of T and Cai systems. Nonlinear feedback control is the method used to achievethe synchronization of the chaotic systems addressed in this paper and our theorems on global exponential synchronization for T and Cai systemsare established using Lyapunov stability theory. Since the Lyapunov exponents are not required for these calculations, the nonlinear feedbackcontrol method is effective and convenient to synchronize identical and different T and Cai systems. Numerical simulations are also given toillustrate and validate the synchronization results for T and Cai systems
