摘要
提出了离散脉冲系统模型,通过分析离散脉冲系统的稳定性,得到了一类拟线性离散脉冲系统全局渐近稳定的充分条件;由此为Lur′e型离散混沌系统的同步提出了一种新的同步方法———离散脉冲同步方法,实现了这类Lur′e型混沌系统的全局同步.以Henon映射混沌系统为例,对所得结论加以验证与仿真实验.
Given is the model of discrete impulsive system and derived are the sufficient conditions under which a class of quasi-linear discrete impulsive system is globally asymptotically stable. On the ba sis of these stability criteria, the discrete impulsive synchronization, which is a new method for chaos synchronization, is given for the chaotic synchronization of the Lur'e-type discrete chaotic systems. The case of the Henon chaotic system is given to illustrate the obtained results.
