摘要:

从多Agent系统的角度,以面向对象Petri网为语义基础,建立了一种信息物理融合系统体系结构模型,将系统抽象为传感器节点Agent、执行器节点Agent和控制器节点Agent.该体系结构模型利用面向对象Petri网形象、无歧义地刻画系统的整体和个体特性,描述系统的静态和动态语义,同时可利用Petri网的数学分析方法和支持工具对系统进行模拟、分析和验证,检测系统开发早期存在的错误,提高系统的正确性和可靠性.利用信息物理融合系统体系结构模型对目标跟踪系统的建模、分析与实现表明,信息物理融合系统体系结构模型可以有效地辅助系统的设计与开发.

Abstract:

A cyber-physical systems architecture model (CPSAM) is set up based on Object-Oriented Petri nets from the point of view of multi-agent systems, which is composed of sensor node agents, actuator agents, and controller agents. The CPSAM can accurately and unambiguously model the overall and individual characteristics, as well as static and dynamic semantics of CPS. Moreover, the CPSAM can be simulated, analyzed and verified by the well-established analysis methods and supporting tools of Petri nets. Consequently, the defects in the early design stage can be detected, and the correctness and reliability can be improved. The modeling, analysis and design of the target tracking systems demonstrate that the CPSAM can effectively design and develop CPS.

Key words: cyber-physical systems, multi-agent systems, Petri nets, analysis
