| 摘 要： | 利用参量自适应法实现了超混沌系统Kawakami映射的同步.通过严密的数学推导,给出了Kawakami映射在单参量自适应下实现同步的充分条件,并在双参量自适应控制下系统同样实现了同步.数值模拟结果显示,该映射输出具有类似于白噪声的宽谱特性,因此比较适合用于保密通信.

| Abstract: | The hyperchaotic systems Kawakami map is synchronized completely using parametric adaptive control algorithm.After a rigorous mathematical deriving,a sufficient condition of the single-parameter adaptive control can be drawn for the synchronization of Kawakami map,and the synchronization is also found in double-parameter adaptive control.The simulation results show that the output signal of this map is similar to the spectrum of white noise,so it can be used in secret communication. |
