耦合混沌电路网络的全局同步机制及电压型耦合的作用

On global mechanisms of synchronization in networks of coupled chaotic circuits and the role of the voltage-type coupling

Ulises Chialva, Walter Reartes

摘要:

研究了耦合Nakano混沌电路的同步模型。中野电路由一个简单的RLC电路与开关电压相关的复位规则,产生一个不连续的动态。因此,我们研究的模型是一个网络的相同的尖峰振荡器集成和消防动力学。振荡器之间的耦合是线性的,但网络取决于振荡器种群的全局状态而受到共同的重置机制的影响。这构成了为这种类型的振荡器构建具有任意拓扑结构的脉冲耦合网络的最简单方式,并且它允许同步状态和不同复位制度的出现。其主要结果是,在一定的假设条件下,在权矩阵(代表网络拓扑结构)上,不同的复位机制相匹配,主稳定性函数的形式可以推广,以研究网络的同步状态和不连续动态的稳定性。此外,中野的电路的低维允许实现的突变矩阵方法和数值模拟可以进行,以分析的作用的耦合模式在网络的同步制度和电压型变量的影响。

英文摘要:

A model for synchronization of coupled Nakano's chaotic circuits is studied. The Nakano circuit consists of a simple RLC circuit with a switch voltage-depending reset rule which generates a discontinuous dynamics. Thus, the model that we study is a network of identical spiking oscillators with integrate-and-fire dynamics. The coupling between oscillators is linear, but the network is subject to a common regime of reset depending on the global state of the oscillator population. This constitutes the simplest way of build pulse-coupled networks with arbitrary topology for this type of oscillators, and it allows the emergence of synchronous states and different reset regimes. The main result is that under certain hypothesis over the weight matrix (that represents the network topology) the different reset regimes match and the formalism of the master stability function can be generalized in order to study the stability of the synchronous state and the discontinuous dynamic of the network. Also, the low dimensionality of the Nakano's circuit allows to implement the saltation-matrix method and numerical simulations can be performed in order to analyze the role of the coupling mode in the synchronization regime of the network and the influence of the voltage-type variables.
