基于极点移动技术的稳定混沌信号实现及应用

Implementation and Application Based on Pole Shifting Technology in Chaotic Control System

首先对最实用的混沌控制若干方法进行了分析,给出了新的改进方法及实现的具体途径。对混沌吸引子中的高周期高维动力系统,采用系统控制论中的极点移动技术,成功实现了混沌控制。文中通过Henon映射提供了一个成功实例,这是一个获得较理想稳定混沌信号源的途径。在混沌通信系统中,数字调制和相关检测有了稳定的混沌信号时可获得更好的实现。

Considering the limitation of conventional OGY method, an improved technology and an implementation based on scientific analysis on chaotic control principle are presented. By using the pole shifting technology, the chaotic system, such as the Henon system can converge at its equilibrium or higher order unstable orbits. The advanced implementation can be obtained since it has the stable and the correlation detect chaotic signal in digital chaotic communication system.
