论文摘要
在本文中，我们提出了一个新颖的框架，用于建模和分析网络离散事件系统（DES）。我们假设该工厂由反馈主管控制，其控制决定受到沟通延迟和损失的影响。此外，我们考虑了一个通用环境，主管通过动态独立的不同通信渠道向不同的执行器发送控制决策。我们通过识别整个网络系统的状态空间并研究整个状态空间的动态来提供系统理论方法。我们的方法精确地指定了主管，通信渠道和执行者的作用。此外，我们将提出的网络DES模型与现有模型进行比较，并表明所提出的网络模型更精确地捕获了网络系统的物理情况。
In this paper, we propose a novel framework for modeling and analysis of networked discrete-event systems (DES). We assume that the plant is controlled by a feedback supervisor whose control decisions are subject to communication delays and losses. Furthermore, we consider a general setting where the supervisor sends control decisions to different actuators via different communication channels whose dynamics are independent. We provide a system theoretic approach by identifying the state-space of overall networked system and investigating the dynamic of the entire state-space. Our approach precisely specifies the roles of the supervisor, the communication channels and the actuators. Also, we compare the proposed networked DES model with the existing one and show that the proposed networked model captures physical situations of networked systems more precisely.
