> 中文摘要: 信息物理融合系统(cyber-physical systems,简称CPS)是深度融合了计算进程和物理进程的统一体,是集计算、通信与控制于一体的下一代智能系统,具有广阔的应用前景.CPS的行为具有混成性、随机性等特征,建模及仿真CPS的动态行为对于开发高质量的CPS系统至关重要.但是目前缺乏面向CPS的领域建模方法及建模CPS的领域建模语言,也迫切需要支持仿真CPS领域模型的仿真工具.针对以上问题,提出一种面向CPS领域的随机混成建模语言(stochastic hybrid modeling language,简称SHML)以支持建模CPS系统的行为.首先,根据CPS的领域特征定义了SHML的元模型作为其抽象语法,并定义了SHML的具体语法和操作语义;其次,基于GEMOC框架实现了SHML的可视化建模工具.此外,集成GEMOC的序列化执行引擎和Scilab的连续行为仿真引擎,实现仿真CPS的混成行为.提出了一种面向CPS领域的建模及仿真方法,设计并实现了一个集成的面向CPS行为的建模与仿真平台,为CPS的建模及仿真提供了一种有效的方法及工具支撑.
Abstract:Cyber-Physical systems (CPS) is a unified entity that deeply integrates computing processes and physical processes. It is a next-generation intelligent system integrating computing, communication, and control. It is widely used in various applications. The dynamic behavior of CPS is always hybrid and stochastic. Modeling and simulating the behaviors of CPS is crucial for developing high-quality CPS. However, it is still lack of domain modeling approach for CPS supporting the construction of CPS domain models and simulation techniques to simulate CPS domain models. To address these issues, this study proposes a domain-specific modeling language for CPS named SHML to support modeling the behaviors of CPS. Firstly, the metamodel of SHML is defined as the abstract grammar according to the domain knowledge of CPS. Moreover, the concrete syntax and the operational semantics are also given. Secondly, based on the GEMOC studio framework, the graphical modeling tool of SHML is implemented. In addition GEMOC sequential execution engine and Scilab engine that can simulate continuous behavior are integrated, which supports the simulating hybrid behavior of CPS. The proposed wrok provides a domain modeling and simulation approach for CPS, which provides an effective approach and tool to support the modeling and simulation for CPS.
