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

项目负责人：George Chiu、Ananth Grama、Christoph Hoffmann和Ahmed sameh该项目的目标是开发(a)用于获取、存档、调节和解释海量数据的计算基础设施，以及(b)用于预测、诊断和动态响应感知数据的算法技术。该项目的长期目标包括开发智能机制和计算技术，用于有效设计和经济施工，用于改造现有结构，以及预测灾难性故障的可能性。我们相信，这种性质的项目将有力地推动下一代传感和驱动系统的发展，并为整个地区的灾害管理提供支持。拟议的项目是探索性的，但可能对结构设计产生深远的影响。虽然人们一直在努力整合实时传感和细粒度控制，但对于这种设计范式是否确实可行，还没有明确的共识。除了潜在的结构机制之外，这些关注还受到与计算和通信基础设施相关的安全性、寿命和功率限制等问题的驱动。这个探索性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.
