摘要
基于Lyapunov-krasovskii泛函理论,研究了Lorenz系统族的自时滞混沌同步问题。理论上对误差系统进行分析,设计出简单通用的时滞同步控制器。通过数值仿真可知,同步收敛速度与控制器的控制参数有密切关系,在给定控制参数的条件范围内系统能达到较满意的同步效果。实验结果表明该方法对一类混沌系统的自时滞同步具有现实可行性。
Based on the Lyapunov-Krasovskii functional theory, self-time-delay chaotic synchronization of Lorenz system families is considered. Through analyzing the error system in theory, a simple and universal time-delay synchronization controller was designed. It was leant from the numerical simulation that convergence speed of synchronization has close relationship with control parameters, and the system synchronization is fairly satisfied within sufficient condition of given control parameters. Results of experiment verified the realistic feasibility of the method of self-time-delay synchronization of class of chaotic systems.
