摘　　要：对单向耦合的统一混沌系统间的投影同步进行了研究与控制 .分析了投影同步现象的产生机理 ,给出一方案对投影同步的特征量进行控制 .该方案所需控制代价较小 ,为设计适当的混沌信号源提供了一种理论依据 ,在利用混沌电路系统进行保密通信方面有着一定的应用前景 .Projective synchronization phenomenon in unidirectionally coupled unified systems is studied. A scheme is proposed to control the scaling factor formed in the projective synchronization. Under the control strategy, one can arbitrarily manipulate the scaling factor to a desired value. This special phenomenon and the control scheme can be used in some secure communication schemes. Illustrations are also given to show the rightness of the theoretical analysis and the effectiveness of the method proposed.
