摘要:

本文对四维非自治的超混沌光学模型的同步问题进行了讨论。结合误差反馈同步方法和参数自适应同步方法,使参数不同的两个系统达到同步,数值计算结果也表明同步效果很好。同时对控制函数的参数与同步建立的时间两者之间的关系进行了仿真,结果表明,存在最佳参数使得同步建立的时间最短。

Synchronization of Non-Autonomous Hyper-chaotic Systems with Parameters Perturbation

()

Abstract:

The synchronization of familiar autonomous chaotic systems, such as Lorenz system and Chua's circuit, to which a great effort has been devoted at present. In this paper, the synchronization of four-dimension non-autonomous hyper-chaotic optical model is discussed. A method for synchronization of two systems with parameters perturbation is presented, which combines the error feedback approach with the parameter adaptive control way. The theoretical results are confirmed by numerical analysis. The simulation shows there exists a group of parameters to reach the shortest synchronization establishment time.
