摘　　要：信息物理系统是一种融合了计算、通信和控制的高级嵌入式系统,其能耗分析方法是目前的热点研究问题。文中针对CPS的模块化架构与其组件能耗的不确定性,提出面向对象模糊Petri网作为一种新的CPS能耗模型。在该模型中,CPS的模块化逻辑结构与功能流程由面向对象技术描述,而其不确定性则通过使用模糊数学理论对模型中的变迁能耗属性进行模糊化的方法来处理。在此基础上,提出了基于OFPN可达标识图的CPS组件能耗分析算法。该算法分析并统计能耗的模糊值后进行解模糊,并输出各组件的最低能耗与最高能耗的精确数值结果。最后通过一个智能厚板生产线的实际CPS案例的建模与能耗分析,进一步说明了该方法的可行性。Cyber-physical system is an advanced embedded system that integrates computing,communication and control functions,and its energy consumption analysis is currently a hot research issue.In view of the modular architecture and the uncertainties of CPS,this study proposes the OFPN as a new energy consumption model of CPS.In OFPN,the modular logical structure and process of CPS are modeled by OFPN,and the uncertainties in CPS is described by using fuzzy mathematics to blur the energy consumption attributes of transitions in OPN.Besides,a CPS component energy consumption analysis algorithm based on the reachability graph of OPFN is proposed,which calculates the fuzzy energy consumptions of each component and then deblur them to get the minimum and maximum numerical results.The availability of the model and analysis method are verified by the modeling and energy consumption analysis of a real-world CPS(an intelligent thick metal plate production line).
