Stress induced polarization switching and coupled hysteretic dynamics in ferroelectric materials
Linxiang WANG, Roderick MELNIK, Fuzai LV
《机械工程前沿(英文)》 2011年 第6卷 第3期 页码 287-291 doi: 10.1007/s11465-011-0230-2
The dynamic responses of ferroelectric materials upon external mechanical and electrical stimulations are inherently nonlinear and coupled. In the current paper, a macroscopic differential model is constructed for the coupled hysteretic dynamics via modeling the orientation switching induced in the materials. A non-convex potential energy is constructed with both mechanic and electric field contributions. The governing equations are formulated as nonlinear ordinary differential equations by employing the Euler-Lagrange equation, and can be easily recast into a state space form. Hysteresis loops associated with stress induced polarization switching and butterfly-shaped behavior in ferroelectric materials are also successfully captured. The effects of mechanical loadings on the electrically induced switching are numerically investigated, as well as the mechanically-induced switching with various bias electric fields.

国内首台ATM(异步转送方式)交换机BTC-9500的研制于1995年完成,并配合国内宽带试验网络的建设,进行了大量的组网试验、设计改进和发展工作。目前,该设备已经由国内最大的电信设备制造商之一——上海贝尔公司生产销售,并且用于装备中国电信宽带骨干网的全部核心节点。根据组网实践中发现的问题,提出了在同一个交换结构内同时实现ATM信元交换和IP数据报交换的方案,并在BTC-9500中予以实现,达到了大大节省设备、简化网络和提高网络速度的多重目的,将研究范围逐渐拓宽到更大的宽带通信领域,提出了对于新一代电信网络发展的一些看法。

时变的网络拓扑结构对多智能体系统的稳定性具有重要的影响。本文研究了在拓扑结构切换情况下,具有“领航者-跟随者”拓扑结构的一般线性多智能体动态系统的稳定性,并将其用于网联汽车的队列控制。为描述多智能体之间的信息交换,本文将切换拓扑建模为关联矩阵特征值均为正实数的有向图,利用黎卡提不等式设计了分布式控制率,并估算了闭环系统的收敛速度。研究提出了具有切换拓扑的多智能体系统稳定性充分判据,同时利用共同李雅普诺夫函数证明了该闭环系统的稳定性。将所得到的结论应用于网联汽车的队列控制,证明了所提出方法的有效性。
