中文摘要：
信息物理融合系统（Cyber-physical system,CPS）是计算、通信和物理过程高度集成的系统,通过在物理设备中嵌入感知、通信和计算能力,实现对外部环境的分布式感知、可靠数据传输、智能信息处理,并通过反馈机制实现对物理过程的实时控制.分析了CPS的基本概念和特征,对CPS的体系架构、中间件系统、实时性、安全和隐私等关键技术的现有研究成果进行综述,并提出了相应的研究思路;然后介绍了一些现有的CPS原型系统和实例,体现出CPS的优越性;最后对CPS和传感器网络（Wireless sensor network,WSN）、物联网（The internet of things,IOT）、网络控制系统（Networked control systems,NCSs）进行了对比分析,总结了CPS现有研究中存在的问题,并展望了CPS的发展方向.
英文摘要：
Cyber-physical system（CPS） represents a system which tightly integrates computation,communication and physical processes.Perception,communication,and computing capabilities are embedded into the physical device,in order to realize distributed sensing,reliable data transfer,intelligent information processing,real-time feedback and control.This paper summarizes the basic concepts and characteristics of CPS firstly,and then gives a systemic review of recent progress on some key technologies,such as architecture,middleware system,real-time feature,security and privacy,and also puts forward some related research ideas.Some prototype systems and practical examples are also described to show the advantages of CPS.Finally,CPS is compared with wireless sensor network（WSN）,the internet of things（IOT）,networked control systems（NCSs）,and some existing deficiencies are summarized,and the future research directions of CPS are proposed.
