摘要
文章针对一类二阶混沌系统,基于微分几何基本理论,提出了一种驱动-响应形状渐近同步的概念.为了实现驱动-响应形状渐近同步,文章首先基于Lyapunov稳定性原理和形状同步误差设计了一种形状同步控制器,并证明了在形状同步控制器作用下,驱动系统和响应系统曲线能够达到形状渐近同步.然后利用形状同步的特点,结合混沌掩盖技术,设计了一种基于形状同步的保密通讯方案.最后,通过仿真验证了形状渐近同步控制应用于保密通讯的有效性.
In this paper,based on basic theory of differential geometry,a definition of driver-response shape asymptotic synchronization is proposed for a class of two-dimensional chaotic system.First,combining Lyapunov stability theory and shape synchronization error,a shape asymptotic synchronization controller is designed.It can be demonstrated that the shape of driver system and response system are able to achieve shape asymptotic synchronization by proposed controller.Then,by utilizing characteristic of shape synchronization,new confidentiality communication scheme with shape synchronization is developed based on chaotic cover technology.Finally,the simulation is given to verify the effectiveness of shape asymptotic synchronization control and its application in confidentiality communication.
