摘要
从对连续时间混沌系统进行数字测量的角度,提出了连续时间混沌系统的采样同步问题.利用控制理论的结果,设计了Lorenz系统族的采样同步系统.仅需测量一个状态分量,就可在采样时刻实现同步.数值模拟例证了同步的性能.
In this paper, sampled-data synchronization of continuous chaotic systems is proposed from the viewpoint of digital measurement of continuous chaotic systems. Based on the results of control theory, a sampled-data synchronization system of Lorenz system families is designed. The synchronization system can synchronize the driven system at sampling points by sampling only one state variable. Numerical simulations illustrated the effectiveness of the synchronization system.
