The focus of this project is on cyber-physical systems (CPS) -- physical and engineered systems whose operations are integrated, monitored, and controlled by a computational core. Applications of CPS include, for example, critical (physical) infrastructure control (electric power, water resources, gas and fuel distribution, transportation, etc.), highly dependable medical devices and systems, traffic control and safety, advanced automotive systems, process control, and manufacturing, energy conservation and environmental control, avionics, distributed robotics (tele-presence, tele-medicine), and manufacturing.Traditional frameworks for designing and configuring computing and networking systems do not capture the complexity of CPS systems -- principally because many of the abstractions developed for computing and networking deliberately abstract away essential properties of the physical world. Existing real-time operating systems (mix of operating systems, middleware, and general-purpose virtual machines) are not sufficient to support the complexity challenges of emerging classes of cyber-physical systems because of the mismatch between traditional computation abstractions and properties of physical processes. Some current technical approaches partially bridge the abstraction gap (such as real-time operating systems, middleware technologies, specialized embedded processor architectures, and specialized networks). However, current research and development of cyber-physical systems calls for non-incremental, revolutionary approaches, where new abstractions are built from the ground up. These abstractions must enable reasoning at every level for high-confidence system composition and addresses issues such as time-criticality, safety, and security.In response to the need for a CPS framework, this SGER project will investigate architectural models with the goal of helping the research community to develop a cyber-physical system vision that integrates both computer science (real-time systems; embedded systems; software and system verification, validation, and certification; computing technologies; wireless and wired networking; sensor nets) and the traditional physical sciences and engineering disciplines (control, physical sensors and actuators, physical system design and engineering, materials, even biology and nanotechnology). Such models are likely to provide a platform for future cyber-physical systems design that brings these interacting elements into a single focus.This project will also sponsor several meetings (workshops, symposia, summit, etc) that aim at providing a forum for engineers and scientists in academia, industry and government to present their latest research findings in any aspects of cyber-physical systems, and, consequently, allow the community to define and enhance the research agenda for this important emerging field. The primary intellectual merit of the proposal resides in analyzing existing cyber-physical systems and developing abstracted architecture models that will enable future cyber-physical systems design and realization. The broader impact of the proposed work is on the research community at-large, through the project focus on issues related to cyber-physical systems. The advancement achieved through this Cyber-physical system research is expected to improve the research and development capabilities in the nation and contribute to increased global competitiveness.

该项目的重点是网络物理系统（CPS） - 物理和工程系统的操作由计算核心集成，监视和控制。 CPS的应用包括，例如，关键（物理）基础​​设施控制（电力，水资源，气体和燃料分配，运输等），高度可靠的医疗设备和系统，交通控制和安全，高级自动系统，工艺控制，能源保护，能源保护和环境控制，环境控制，环境控制，电视机器人和制造机器人，电视机器人和制造机构，以及电视机构，电视连接。系统不会捕获CPS系统的复杂性 - 主要是因为为计算和网络开发的许多抽象故意抽象物理世界的基本属性。由于传统的计算抽象和物理过程的属性之间的不匹配，现有的实时操作系统（操作系统，中间件和通用虚拟机的混合）不足以支持新兴类别的网络物理系统的复杂性挑战。一些当前的技术方法部分弥合了抽象差距（例如实时操作系统，中间件技术，专门的嵌入式处理器架构和专用网络）。但是，当前的网络物理系统的研究和开发要求采用非附加性，革命性的方法，从而从头开始构建新的抽象。 These abstractions must enable reasoning at every level for high-confidence system composition and addresses issues such as time-criticality, safety, and security.In response to the need for a CPS framework, this SGER project will investigate architectural models with the goal of helping the research community to develop a cyber-physical system vision that integrates both computer science (real-time systems; embedded systems; software and system verification, validation, and certification; computing technologies; wireless and有线网络；传感器网）以及传统的物理科学和工程学科（控制，物理传感器和执行器，物理系统设计和工程，材料，甚至生物学和纳米技术）。 Such models are likely to provide a platform for future cyber-physical systems design that brings these interacting elements into a single focus.This project will also sponsor several meetings (workshops, symposia, summit, etc) that aim at providing a forum for engineers and scientists in academia, industry and government to present their latest research findings in any aspects of cyber-physical systems, and, consequently, allow the community to define and enhance the research agenda for这个重要的新兴领域。该提案的主要智力优点在于分析现有的网络物理系统和开发抽象的体系结构模型，这些模型将使未来的网络物理系统设计和实现。拟议工作的更广泛影响是通过项目关注与网络物理系统有关的问题，对研究社区的广泛影响。通过这项网络物理系统研究取得的进步有望提高全国的研发能力，并有助于增加全球竞争力。
