Observer-Based Synchronization of Chaotic Complex Systems

A unified mathematical expression describing a class of chaotic complex systems is presented, for which the issue about synchronization of chaotic complex systems is discussed. Based on the nonlinear state observer and the pole placement technique, observer-based synchronization scheme is designed. The synchronization of chaotic complex systems is achieved via this observer controller. The efficiency of the proposed synchronization scheme is confirmed by numerical simulations of two well known chaotic complex systems: complex Lorenz system and complex two coupled dynamos system.
