Abstract:

A new parameter variation chaotic synchronization method based on parameter variation chaotic synchronization conditions is persented.Only one variable of driving system is used in the method, feedback control and adaptive control methods are also used to guarantee the chaotic synchronization.The method need not parameter identification and use only part of variable of driving system which loosen the restriction conditions of chaotic synchronization. The Lorenzs group chaotic system is considered,theorem on the sufficient conditions for attaining chaotic synchronization has been proposed. The simulations have shown the effectiveness and feasibility of the method.

Key words: chaotic synchronization, single variable, frequency estimation
