CPS: Medium: Collaborative Research: CyberMech, a Novel Run-Time Substrate for Cyber-Mechanical Systems

CPS：中等：合作研究：CyberMech，一种新型的网络机械系统运行时基板对我们民用基础设施的需求不断增长，提高了对智能结构部件和系统的需求，这些部件和系统的行为和性能可以在各种负载情况下进行控制，如大风和地震。然而，由于大多数土木工程结构的庞大规模，规模和成本，这种智能结构的设计和测试需要使用混合网络物理方法进行，其中所讨论的基础设施系统，例如桥梁，通过将少量的物理组件与结构其余部分的数值模型相耦合来研究。毫无疑问，这种混合方法的成功，特别是对于动态实时应用，取决于系统的网络和物理组件的有效集成。该项目提供了必要的构建模块和计算集成平台，以实现土木工程结构的实时混合测试。物理组件、多层次数值模型和实时控制算法的设计和开发将在普渡大学进行。华盛顿大学将提供一个自适应的、可配置的并发平台和通信机制，以满足实时网络物理系统的严格调度约束。这两个机构将合作设计一个原型系统，并进行广泛的测试，以验证各种组件的集成并评估系统性能。在此项目过程中开发的规范、软件、基准和数据将免费提供给网络物理研究社区。除了直接推进实时混合动力测试的最新技术外，这项研究还将影响航空电子、汽车设计、分布式输电智能电网以及其他领域的类似应用。

CPS: Medium: Collaborative Research: CyberMech, a novel run-time substrate for cyber-mechanical systemsGrowing demands on our civil infrastructure have heightened the need for smart structural components and systems whose behavior and performance can be controlled under a variety of loading scenarios such as high winds and earthquakes. However, due to the sheer size, scale and cost of most civil engineering structures, design and testing of such smart structures needs to be conducted using a hybrid cyber-physical approach where the infrastructure system in question, for example a bridge, is studied by coupling a small number of physical components with a numerical model of the rest of the structure. Undoubtedly, the success of such a hybrid approach, especially for dynamic real-time applications, hinges on effective integration of the cyber and physical components of the system. This project provides the essential building blocks and a computational integration platform to enable real-time hybrid testing of civil engineering structures.Design and development of physical components, multi-level numerical models, and real-time control algorithms will be conducted at Purdue University. Washington University will provide an adaptive, configurable concurrency platform and communication mechanisms that meet the strict scheduling constraints of real-time cyber-physical systems. The two institutions will collaboratively design a prototype system and conduct extensive testing to validate the integration of the various components and evaluate system performance. Specifications, software, benchmarks, and data developed during the course of this project will be made freely available to the cyber-physical research community. In addition to directly advancing the state-of-the-art in real-time hybrid testing, this research will also impact the areas of avionics, automotive design, smart grids for distributed power transmission and similar applications in other domains.
