应用计算机仿真研究混沌及混沌同步

在混沌应用研究领域，计算机仿真方法是继数值分析法、Lyapunov指数分析法和真实实验法之后的另一个非常有效而实用的混沌研究方法。本文通过计算机仿真再现了Chua电路的混沌信号输出；实现了对两个Chua电路主动－被动混沌同步。仿真实验表明：（i)在研究电子学信号混沌系统的混沌同步问题时，仿真实验与真实实验有较好的对等性；；（ii）在仿真实验过程中，仿真方法对影响系统同步的因素（如噪声和系统参数变化等因素）能进行有较控制，较之真实实验，对系统的稳定性和鲁棒性问题能进行更准确的量化分析。

The Application of Computer Simulation in Studying Chaos and Chaos Synchronization

In the study of chaos and chaos app lications,the methods of numerical analysis,Lyapunov exponential analysis and re al experiment analysis are extensively used.Recently,computer simulation is prov ed very efficient and practical.For the famous Chua's circuit, chaos signals output and chaos synchronzation reappeare by computer simulation i n the paper.The simulation results indicate:(i)The simulation is precise and has reciprocity in the real experiment of chaos systems construct ed with electronic circuits;(ii)The system parameters are cont rolled more easily in simulation,so the stability and robustness of the system a re more precisely analyzed.
