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.
For a class of supply chain inventory system, the closed-loop stability problem of the system is studied. The innovation point is that the supply chain inventory system is modeled as a networked delay control system by introducing the idea of network control. On the premise of knowing the packet loss rate, the stability of supply chain inventory system is analyzed through the design of network controller. The sufficient conditions for the asymptotic stability of supply chain inventory system are given by using the free weights matrix and Lyapunov stability theory The feasibility and validity of the proposed control scheme are verified by numerical simulation.
