| 摘 要： | 针对时滞混沌系统的同步问题,利用脉冲控制方法,提出了新的渐进同步的充分条件。利用脉冲状态反馈控制,在系统矩阵为Hurwitz矩阵和正定矩阵两种情况下,得到了时滞混沌系统同步的充分条件;进一步,为便于工程应用,利用脉冲输出反馈,在系统矩阵为上述两种情况下,得到了时滞混沌系统同步的充分条件。该同步条件使时滞混沌同步系统快速地达到10-2误差。最后,以一个多重时滞混沌系统为例,进行了数值仿真,验证了该方法的有效性。

| Abstract: | To investigate synchronization for time-delayed chaotic system,some novel sufficient conditions of asymptotical synchronization are proposed by virtue of impulsive control.Using impulsive state feedback control,some sufficient conditions of time-delayed chaotic systems are obtained when system matrix is Hurwitz or positive definite.Furthermore,to be convenient for engineering application,using impulsive output feedback,some sufficient conditions are derived when system matrix is above-mentioned.The synchronization errors of time-delayed chaotic synchronization system reach quantitatively 10-2 with the proposed conditions.Finally,to demonstrate the validity of the proposed methods,numerical simulation is carried out via taking multiple time-delayed chaotic system as an example. |
