网络动力系统遍布于国家基础设施中,例如国家电网、污水处理网络和国家交通系统。随着这些网络规模的增长,网络上的弱耦合可能开花成系统范围的干扰,其影响在大的地理区域内感受到。因此,各国迫切需要设计出更强有力和成本效益更高的技术来管理这种联网系统。该项目通过自我触发的分散控制方法来满足这一需求。在这种方法中,网络子系统使用它们当前的状态信息来确定信息必须交换的速率,以确保网络化系统?的全局L2稳定性。这些速率被视为网络上的服务质量(QoS)约束?的交通。这个项目使用这些QoS约束,开发软实时算法调度网络控制系统中的消息传递。这项工作的新颖之处在于,所得到的软实时控制系统提供了传统上在硬实时系统中看到的应用程序性能的保证。该项目正在通过与工业界合作,将自触发技术转让给私营部门,该项目使用嵌入式传感器-致动器网络来控制下水道溢流(CSO)事件的频率。这个CSO网络是网络化信息物理系统的一个很好的例子。为支持培训有资格管理此类系统的工程师,该项目正在编制一套关于网络物理系统数学基础的讲座。
英文摘要
Networked dynamical systems are found throughout the national infrastructure.Examples of such systems are seen in the national power grid, wastewater networks, and the national transportation system. As these networks grow in size, weak coupling across the network can blossom into system wide disturbances whose effects are felt over large geographical regions. There is, therefore, a compelling national need to devise more robust and cost-effective techniques for managing such networked systems. This project addresses this need through a self-triggered approach to decentralized control. In this approach, network subsystems use their current state information to determine the rate at which information must be exchanged to assure the networked system?s global L2 stability. These rates are cast as quality-of-service (QoS) constraints on the network?s traffic. This project uses these QoS constraints to develop soft real-time algorithms for scheduling message passing in networked control systems. The novel aspect of this work is that the resulting soft real-time control system provides guarantees on application performance that have traditionally been seen in hard real-time systems. The project is transferring the self-triggered technology to the private sector through collaborations with industry on a project that uses embedded sensor-actuator networks to control the frequency of combined-sewer-overflow (CSO) events. This CSO network is a good example of a networked cyber-physical system. To support the training of engineers qualified to manage such systems, this project is developing a set of lectures on the mathematical foundations of cyber-physical systems.
