Reaserch on Chaotic Synchronization Method of Secure Communication Based on Time-Varying Delay

针对固定时间延迟及时变时间延迟系统,提出了同步控制方案,在实现同步后能有效解决传输时延对保密通信的影响.利用线性矩阵不等式方法设计了同步控制器,应用Lyapunov方法分析了同步误差的收敛性,并运用Schur补引理证明了全局渐近稳定点的存在.

A synchronization control scheme is proposed for time-varying delayed chaotic secure communication system.When the synchronization of time-varying delayed is achieved,the secure information can be efficiently recovered.The synchronization controller is proposed using linear matrix inequality technology,the convergence of the synchronization error is analyzed using the Lyapunov method and the existence of global stability point is proved using schur complement lemma.
