本文利用周期平均法给出了一类具有快标量变量的快慢非线性系统部分指数稳定性的新判据。与经典的平均技术不同,我们通过对这个快速标量变量而不是时间变量进行平均来构建平均系统。我们表明,部分指数稳定的平均系统意味着原来的。然后,我们将得到的标准的研究耦合的星星网络与两个外围节点的Kuramoto-Sakaguchi振荡器的远程同步。我们发现,失谐的中央调解振荡器的自然频率增加了对相移的远程同步的鲁棒性。这篇文章似乎是第一个已知的尝试,分析研究相位解锁远程同步。
This article presents some new criteria for the partial exponential stability of a slow–fast nonlinear system with a fast scalar variable using periodic averaging methods. Unlike classical averaging techniques, we construct an averaged system by averaging over this fast scalar variable instead of the time variable. We show that the partial exponential stability of the averaged system implies that of the original one. We then apply the obtained criteria to the study of remote synchronization of Kuramoto–Sakaguchi oscillators coupled by a star network with two peripheral nodes. We show that detuning the natural frequency of the central mediating oscillator increases the robustness of the remote synchronization against phase shifts. This article appears to be the first-known attempt to analytically study the phase-unlocked remote synchronization.
