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第三代网络控制系统的平台革命相关的问题。该方法是解决四个基本问题：（一）如何提供延迟保证通信网络，以支持网络控制？(ii)如何在网络上同步时钟，以实现一致和及时的控制行动？(iii)什么是一个合适的架构，以支持可靠而灵活的控制系统设计机制？(iv)如何在网络和物理域中提供正确性能的跨域证明？智力优点：目前，无论是理论还是网络协议都没有为具有延迟约束的通信提供解决方案。时间协调是下一代网络物理系统所构成的事件和时间驱动系统的基础。管理架构中的延迟和时序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影响。实现对网络的控制将产生新的大规模应用，例如，通过联网高速公路上行驶的汽车来开发零死亡高速公路系统的巨大挑战。这项研究将培养研究生对网络控制这一新技术。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，以及其他本科和高中研究人员，（ii）每年在工程开放日接待数百名高中/初中/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.
