CPS: Breakthrough: Robust Team-Triggered Coordination for Real-Time Control of Networked Cyber-Physical Systems

该项目的目的是奠定了一种新的方法来实时控制网络化的信息物理系统（CPS），利用他们的合作性质的基础。 大多数网络控制器不能在嵌入式数字计算机系统上实现，因为它们依赖于执行成本高昂的连续时间或同步执行。这些假设是不切实际的，当面对网络物理世界，计算和物理组件之间的相互作用是多元化的，信息采集是受错误和延迟，代理时间表是异步的。即使没有执行障碍，定期提供信息也会导致资源的浪费。调整控制器执行手头的任务提供了极大的节省通信，传感和驱动的潜力。 该项目的目标是通过将事件触发和自触发控制思想结合到一个统一的方法中，继承两种模型的优点，从而实现这一机会。关键的概念新奇在于，智能体相互承诺未来的状态，并在以后决定违背承诺时相互警告。Promise所提供的信息使智能体能够自主决定何时需要新的信息，从而实现高效的网络性能。网络化的信息物理系统正在改变社会与物理世界的交互方式。这一领域的进步正在扩大人类在越来越多具有高度社会和经济影响的领域的能力范围，如智能能源，智能交通，先进制造，健康技术和环境。 该项目通过为网络系统开发一种新的原则性方法来促进网络物理系统的科学和技术，以有效地运行并科普现实应用中存在的不确定性来源。 潜在的好处是实时操作在广泛的应用领域的合作网络物理系统与上级水平的效率和鲁棒性比目前可能的。该项目承诺将有助于培养新一代的工程专业学生在加州大学圣地亚哥分校与必要的技能，以处理这种类型的多方面的系统和应用程序。 该计划包括本科生参与研究，研究生监督和课程开发，向高中生推广，保留STEM学科中的少数民族，以及广泛的传播活动。

The aim of this project is to lay down the foundations of a novel approach to real-time control of networked cyber-physical systems (CPS) that leverages their cooperative nature. Most networked controllers are not implementable over embedded digital computer systems because they rely on continuous time or synchronous executions that are costly to enforce. These assumptions are unrealistic when faced with the cyber-physical world, where the interaction between computational and physical components is multiplex, information acquisition is subject to error and delay, and agent schedules are asynchronous. Even without implementation obstacles, the periodic availability of information leads to a wasteful use of resources. Tuning controller execution to the task at hand offers the potential for great savings in communication, sensing, and actuation. The goal of this project is to bring this opportunity to fruition by combining event- and self-triggered control ideas into a unified approach that inherits the best of both models. The key conceptual novelty is for agents to make promises to one another about their future states and warn each other if they later decide to break them. The information provided by promises allows agents to autonomously determine when fresh information is needed, resulting in an efficient network performance.Networked cyber-physical systems are transforming the way society interacts with the physical world. Advances in this field are extending the range of human capabilities in an increasing number of areas with high societal and economic impact, such as smart energy, intelligent transportation, advanced manufacturing, health technology, and the environment. This project contributes to the science and technology of cyber-physical systems by developing a novel principled approach for networked systems to operate efficiently and cope with the sources of uncertainty present in real-word applications. The potential benefits are real-time operation in a wide range of application domains of cooperative cyber-physical systems with a superior level of efficiency and robustness than currently possible. The project promises to contribute to the training of a new generation of engineering students at UC San Diego with the skills necessary to deal with this type of multi-faceted systems and applications. The plan includes undergraduate student involvement in research, graduate supervision and curriculum development, outreach to high-school students, retention of minorities in STEM disciplines, and broad dissemination activities.
