最近邻非全同vanderPol-like振子同步流形的稳定性

Stability of the synchronization manifold in nearest neighbors non identical van der Pol-like oscillators

R. Yamapi, H. G. Enjieu Kadji, G. Filatrella

摘要:

我们研究了环和最近邻耦合自持系统的开放链中同步流形的稳定性,每个自持系统由多个极限环van der Pol振子组成.这种模型代表,例如,在生物系统中的相干振荡,通过在脑波模型中的铁电行为的酶底物反应的情况下。分别考虑全同振子和非全同振子的环和开环链。通过使用主稳定性函数方法(对于相同的情况)和复Kuramoto序参量(对于不相同的情况),我们得到了同步流形的稳定性边界。我们发现,同步发生在一个系统中的许多耦合的修改vanderPol振荡器,它是稳定的,即使在存在的传播参数。

英文摘要:

We investigate the stability of the synchronization manifold in a ring and an open-ended chain of nearest neighbors coupled self-sustained systems, each self-sustained system consisting of multi-limit cycles van der Pol oscillators. Such model represents, for instance, coherent oscillations in biological systems through the case of an enzymatic-substrate reaction with ferroelectric behavior in brain waves model. The ring and open-ended chain of identical and non-identical oscillators are considered separately. By using the Master Stability Function approach (for the identical case) and the complex Kuramoto order parameter (for the non-identical case), we derive the stability boundaries of the synchronized manifold. We have found that synchronization occurs in a system of many coupled modified van der Pol oscillators and it is stable even in presence of a spread of parameters.
