基于网络控制的供应链库存系统的稳定性分析

针对一类供应链库存系统,研究了系统的闭环稳定性问题.创新点在于通过引入网络控制的思想,把供应链库存系统建模成网络时滞控制系统.在网络诱导时滞的上下界和丢包率已知的前提下,通过网络控制器的设计,分析了供应链库存系统的稳定性,并利用自由权矩阵和Lyapunov稳定性理论,给出了供应链库存系统渐近稳定的充分条件,并通过数值仿真验证了所提控制方案的可行性和有效性.

Analysis on Stability of Inventory System in Supply Chain Based on Network Control Approach

For a class of inventory systems in supply chain,the problem of stability is considered.The main contribution of this note is that production system of supply chain is modeled as network time-delay system by pulling the idea of network control into the supply chain.The controller is designed that stabilizes the inventory system under knowing the upper and lower bounds and the rate of data dropout.The sufficient conditions are given based on free weighted matrix and Lyapunov stability theory.The numerical example is provided to show the effectiveness of the proposed method.
