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 he used in secret communication.

Key words: hyperchaos, weak chaos, parametric adaptive control algorithm, Lyapunov characteristic exponent, chaos synchronization, spectrum
