SGER: Towards Real-Time Sensing and Control of Active Structures

走向结构的实时传感和控制首席研究员：梅特·索森联合首席研究员：乔治邱，Ananth Grama，克里斯托弗·霍夫曼和艾哈迈德·萨梅本项目的目标是开发（a）用于采集，存档，调节和解释大量数据的计算基础设施和（B）用于预测，诊断和动态响应传感数据的算法技术。其长期目标包括开发智能机制和计算技术，以实现有效的设计和经济的施工，改造现有结构，并预测灾难性故障的可能性。我们相信，这类项目将为下一代传感和驱动系统的发展提供强大的动力，并为区域灾害管理提供支持。拟议项目是探索性的，但可能对结构设计产生深远的影响。虽然已经有旨在集成实时传感和细粒度控制的努力，但对于这种设计范式是否确实可行，还没有明确的共识。除了基本的结构机制之外，这些问题的动机是与计算和通信基础设施相关联的安全性、寿命和功率约束的问题。这个探索性的项目并不旨在解决所有这些问题，但它侧重于构建传感基础设施和探索鲁棒实时分布式控制的可行性的核心问题。

Towards Real-Time Sensing and Control of StructuresPrincipal Investigator: Mete SozenCo-Principal Investigators: George Chiu, Ananth Grama, Christoph Hoffmann,and Ahmed SamehThe goal of this project is to develop (a) the computational infrastructure for acquisition, archival, conditioning, and interpretation of massive data and (b) algorithmic techniques for prognostic, diagnostic, and dynamic response to sensed data. The long-term goals of the include the development of smart mechanisms and computational techniques for the effective design and economical construction, for retrofitting existing structures, and prognostication of the likelihood of catastrophic failures. It is our belief that a project of this nature will provide strong impetus to the development of next generation sensing and actuation systems, as well as provide support for area-wide disaster management.The proposed project is exploratory but may have a profound impact on structural design. While there have been efforts aimed at integrating real-time sensing and fine-grained control, no clear consensus exists on whether such a design paradigm is indeed feasible. In addition to the underlying structural mechanisms, these concerns are motivated by issues of security, longevity, and power constraints associated with the computing and communications infrastructure. This exploratory project does not aim to address all of these issues, but it focuses on the core issues of building a sensing infrastructure and exploring the feasibility of robust real-time distributed control.
