摘要
针对无法通过传送单一(路)信号实现同步的低维混沌系统及超混沌系统同步,以及一些混沌同步系统同步时间较长的问题,采用旋转坐标变换法对混沌系统进行改进。该方法是一种线性变换,变换过程不改变原系统自身性质,而是通过引入适当的变换角度和幅度使系统同步的性质发生改变,同时同步质量也得到提高。对三维Rossler混沌系统和超混沌系统进行旋转坐标变换的仿真结果表明,可以通过此方法对一些无法实现同步的低维混沌系统及超混沌系统结构进行改造,从而使系统达到同步,提高混沌系统的同步速率。
An idea of varying rotation coordinates to improve the property of chaos system is presented to solve the problem of some low-dimension chaotic systems and super-chaotic systems, which can not come approach to the state of synchronization and abbreviates synchronization time. This linear transformation doesn not change the property of the system, by using appropriate varying angle and breath to improve the synchronization property. By simulating Rossler system and its super-chaotic system, the method can raise the synchronous speed. The action can not only improve the synchronous effect of chaos system and super-chaotic system, but also help us to design more applicable system.
