Cyber-Physical Systems: Monitoring, Control, and Optimization

信息物理系统（CPS）是与物理过程/环境接口的工程计算和通信系统。随着计算和网络技术的爆炸式增长，CPS在许多现代应用中被发现，包括无线过程自动化、电网、交通网络、先进的汽车系统、环境监测、医疗器械、无线传感器网络和分布式机器人。在CPS中，诸如致动器、传感器、子系统和控制器之类的系统元件通常在空间上彼此隔离，以异步方式操作并且经由有线和无线链路在广域上通信。由于控制、计算和通信组件之间的相互作用，此类系统为控制工程师和设计师带来了新的挑战：（a）如何探索外部计算能力以获得更好的系统完整性？(b)何时连接不同的系统元素以有效利用通信资源？(c)何时以及如何执行分布式控制以获得更好的全局性能？在CPS中集成控制规范、计算能力和通信约束是本研究的目标和推力。我们提出了一个分布式的，事件触发的控制和通信范式CPS的研究计划涵盖通信约束下的状态估计，事件触发的反馈控制，事件触发的多智能体系统，并在无线自动化中的应用。拟议的研究计划将填补理论与实践之间的差距，它将提供控制工程师与CPS的分析和合成的新工具，它将有利于一个团队的研究生和博士后研究员从事技术和行业相关的研究培训，最后，它将建立和加强加拿大的领先地位，在这个新的和新兴的研究竞技场的CPS监测和控制。

Cyber-physical systems (CPS) are engineered computing and communicating systems that interface with physical processes/environment. With the explosive growth in computing and networking technology, CPS are found in many modern applications, including wireless process automation, electrical power grids, transportation networks, advanced automotive systems, environmental monitoring, medical appliances, wireless sensor networks, and distributed robotics. In CPS, the system elements such as actuators, sensors, subsystems, and controllers are typically spatially isolated from one another, operating in an asynchronous manner and communicating over a wide area via both wired and wireless links. Such systems present new challenges for control engineers and designers because of the interactions among control, computation, and communication components: (a) How to explore outside computing capability for better system integrity? (b) When to connect different system elements for efficient use of communication resources? (c) When and how to execute distributed control for better global performance? Integrating control specifications, computation capabilities, and communication constraints together in CPS is the objective and thrust in this research. We propose a distributed, event triggered control and communication paradigm for CPS; the research program covers state estimation under communication constraints, event triggered feedback control, event triggered multi-agent systems, and application in wireless automation. The proposed research program would fill in the gap between theory and practice; it would provide control engineers with new tools for analysis and synthesis of CPS; it would benefit a team of graduate students and post-doctoral fellows by engaging in technology- and industry-relevant research training; finally, it would establish and strengthen Canada's leading position in this new and emerging research arena of CPS monitoring and control.
