长时延NCS的结构特性与建模

The Configuration and Model for Long Delay NCS

研究网络控制系统的关键问题包括两个方面:控制算法和网络结构,其中网络结构决定了系统可靠性和稳定性,系统的实时性也取决于网络结构(包括拓扑结构和协议结构),建立网络结构模型是研究NCS的前提,文章介绍了典型的网络结构和结构抽象化描述方法,并分析了针对长时延的数学模型,该成果对研究NCS有很重要的意义。

The two key problems of networked control system include control arithmetic and network configuration.The system reliability and stability depend on the network reconfiguration that includes topology and protocol.The precondition on NCS is establishing network reconfiguration mathematic model.In this paper,typical network framework and abstract description method is put forward and the mathematic model on long delay is analyzed.The result is very important to study NCS.
