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.

迈向结构的实时感知和控制首席研究员：Mete Sozen联合首席研究员：George Chiu、Ananth Grama、Christoph Hoffmann和Ahmed Same这个项目的目标是开发(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、诊断和动态响应传感数据的算法技术。其长期目标包括开发智能机构和计算技术，以进行有效的设计和经济的建造，改造现有的结构，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推动下一代传感和驱动系统的发展，并为区域范围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影响。虽然已经有了旨在将实时传感和细粒度控制相结合的努力，但对于这种设计范例是否确实可行，还没有明确的共识。除了基本的结构机制外，这些担忧还受到与计算和通信基础设施相关的安全、寿命和功率限制等问题的推动。这个探索性项目的目的并不是解决所有这些问题，但它侧重于建立传感基础设施和探索稳健的实时分布式控制的可行性的核心问题。
