摘要
利用非线性系统混沌同步理论,研究了一类拓扑不等价混沌系统之间的广义混沌同步。对一类拓扑不等价混沌系统,通过设计一个合适标量控制器,可以实现不同混沌系统之间的广义同步。给出了从混沌系统得到该标量控制器设计的一般方法,并利用严格数学理论得到了广义同步的充分必要争件,并论证了该充分和必要条件与混沌系统的性质无关。
Using nonlinear chaotic synchronization theory, the generalized chaotic synchronization between a class of topologically inequivalent chaotic systems is studied. Adding a suitable scalar controller to a class of topologically inequivalent chaotic systems, the chaotic synchronization between those topologically inequivalent chaotic systems can be realized. The method of obtaining the scalar controller from topologically inequivalent chaotic systems is presented; at the same time, the sufficient and necessary condition of chaotic synchronization is obtained. More important- ly, it is proved that the sufficient and necessary condition is independent of the character of chaotic systems.
