CPS: Small: Delays, Clocks, Timing and Reliability in Networked Control Systems: Theories, Protocols and Implementation

摘要本研究的目的是解决与导致第三代网络控制系统的平台革命相关的问题。方法是解决四个基本问题：(i)如何在通信网络上提供延迟保证以支持网络化控制？（ii）如何在网络上同步时钟，以便采取一致和及时的管制行动？（iii）支持可靠而灵活的控制系统设计机制的适当架构是什么？（iv）如何在网络和物理领域提供适当性能的跨域证明？智力优势：目前，无论是理论还是网络协议都没有提供具有延迟约束的通信解决方案。时间协调是网络物理系统构成的下一代事件和时间驱动系统的基础。在架构中管理延迟和定时是网络物理系统的基础。更广泛的影响：过程、航空航天和汽车行业严重依赖反馈控制回路。任何平台革命都将产生重大后果。实现对网络的控制将带来新的大规模应用，例如，通过在高速公路上行驶的汽车联网来开发零死亡公路系统的巨大挑战。本研究将训练研究生掌握网络控制的新技术。融合实验室(i)雇用了少数民族本科生，包括罗恩·麦克奈尔学者，以及其他本科生和高中研究人员，（ii）每年在工程开放日接待数百名高/中/小学学生。研究结果将在会议上发表，并在公开文献中发表。

AbstractThe objective of this research is to address issues related to the platform revolution leading to a third generation of networked control systems. The approach is to address four fundamental issues: (i) How to provide delay guarantees over communication networks to support networked control? (ii) How to synchronize clocks over networks so as to enable consistent and timely control actions? (iii) What is an appropriate architecture to support mechanisms for reliable yet flexible control system design? (iv) How to provide cross-domains proofs of proper performance in both cyber and physical domains?Intellectual Merit: Currently neither theory nor networking protocols provide solutions for communication with delay constraints. Coordination by time is fundamental to the next generation of event-cum-time-driven systems that cyber-physical systems constitute. Managing delays and timing in architecture is fundamental for cyberphysical systems. Broader Impact: Process, aerospace, and automotive industries rely critically on feedback control loops. Any platform revolution will have major consequences. Enabling control over networks will give rise to new large scale applications, e.g., the grand challenge of developing zero-fatality highway systems, by networking cars traveling on a highway. This research will train graduate students on this new technology of networked control. The Convergence Lab (i) has employed minority undergraduate students, including a Ron McNair Scholar, as well as other undergraduate and high school researchers, (ii) hosts hundreds of high/middle/elementary school students annually in Engineering Open House. The research results will be presented at conferences and published in open literature.
