摘要
应用分数阶微积分稳定性理论,提出了一类分数阶超混沌系统同步控制的新方法,通过在分数阶超混沌响应系统中设计两个控制器,实现了分数阶超混沌Chen系统之间的同步。并将该方案应用到保密通信中,利用混沌掩盖技术,实现了复杂非周期信号的安全传送,在接收端通过去掩盖,毫无失真地恢复了有用传送信号。数值仿真和理论分析结果的一致性表明了该方案的有效性和可行性。
Using the stability theory of fractional calculus, the paper proposes a new control method for the synchronization of the fractional-order hyperchaotic system. In the paper, the synchronization between two identical fractional-order Chen hyperchaotic systems is realized by designing only two suit- able controllers in the response system. Furthermore, this control scheme can be used in secure commu- nication via the technology of chaotic masking using the complex non-periodic information as trial mes- sage, and the useful information can be recovered at the receiver. Numerical simulations coincide with the theoretical analysis results, demonstrating the effectiveness and feasibility of the proposed method.
