Engineering Research Equipment: Data Acquisition, Sensing & Control

9500301斯宾塞这个项目是购买一个数据采集和分析系统，将致力于跨学科的研究工程。 这些设备将用于支持NSF赞助的正在进行的主动、半主动和混合控制结构的研究工作，以减轻地震灾害。 数据采集系统将允许精确地确定数学模型（线性和/或非线性），由此可以开发适当的控制策略。 这种模型是必不可少的，因为许多最有前途的控制设备本质上是非线性和滞后的。 该设备预计将加速开发的控制设备/策略，可实施的全尺寸结构，并允许规定的建模不确定性和错误被引入到评估的鲁棒性和性能的控制结构。 ***

9500301 Spencer This project is to purchase a data acquisition and analysis system which will be dedicated to inter-disciplinary research in engineering. The equipment will be used to support ongoing NSF sponsored research efforts on active, semi-active and hybrid control of structures for earthquake hazard mitigation. The data acquisition system will allow for accurate determination of mathematical models (both linear and/or nonlinear) from which appropriate control strategies can be developed. Such models are essential, since many of the most promising control devices are intrinsically nonlinear and hysteretic. This equipment is expected to accelerate development of control devices/strategies that are implementable in full-scale structures and to allow prescribed modelling uncertainties and errors to be introduced to asses the robustness and performance of the controlled structure. ***
