Synchronization Between an Integer Orders Chaotic System and Fractional-order Optically Injected Semiconductor Lasers Model

摘要/Abstract

摘要:

为利用混沌同步提高通讯系统的安全性,以一个三维整数阶混沌系统作为驱动系统、分数阶半导体激光器系统作为响应系统,研究了二者之间的混沌同步.分析了2个系统的混沌行为,给出了不同相平面上系统的混沌吸引子;基于分数阶系统稳定性理论,为系统设计了合适的反馈同步控制器,实现了系统间的混沌同步;数值仿真验证了所设计控制器的有效性.

Abstract:

In order to make use of chaos synchronization to enhance the security of communication system,the chaos synchronization between a three-dimensional integer orders chaotic system and fractional-order optically injected semiconductor lasers model are studied.The chaotic characteristic of two system is investigated with nonlinear dynamics theory,and chaotic attractors in different phase space are got by numerical simulation.Based on the fractional stability theory,suitable adaptive synchronization controller is designed.Numerical simulations show the effectiveness and feasibility of the controllers.
