Complete Synchronization Control of FHN Circuits in Series of Capacitor-coupled Photocells

摘要/Abstract

摘要：

混沌现象是自然界中普遍存在的非线性动力系统的独特行为，混沌同步现象在电子学、医学和保密通信等领域应用广泛.首先，在FHN电路的电容器所在支路上通过串联一个光电管来模拟感光神经元，有效增强了神经元电路的物理响应，并对其动力学行为进行分析发现，该电路在不同的外界刺激作用下可以出现不同的放电状态.其次，通过数值模拟分类讨论了，电容器耦合两个相同放电态耦合系统的完全同步现象以及两个不同放电态耦合系统的完全同步现象.结果表明,合适的耦合强度可以使两个相同的放电态耦合系统达到完全同步，但不能使两个不同的放电态耦合系统实现同步.该电路可以产生更复杂的混沌行为，因此通信保密性更强，所得结果可以为保密通信研究提供参考价值.

Abstract：

Chaos is a unique behavior of a nonlinear dynamical system that exists in nature,and chaos synchronization is widely used in electronics,medicine,and secure communication.In this paper,a pho-totube is connected in series on the branch where the capacitor of the FHN circuit is located to simulate the photosensitive neuron,which effectively enhances the physical response of the neuronal.Its dynamic behavior is analyzed.It is found that the circuit can appear in different discharge states under various external stimuli.The complete synchronization of two same discharge coupling systems and two different discharge coupling systems is discussed by numerical simulation classification.The results show that two same discharge coupling systems can achieve complete synchronization,but two different discharge coupling systems cannot achieve synchronization.The circuit can produce more complex chaotic behavior,Which makes the communication security be more robust.The research in this paper for secure communication.
