Active Control of Floor Vibration

9503369哈纳根的过度地板振动在许多类型的建筑结构中并不少见。之前在弗吉尼亚理工学院和州立大学进行的研究已经利用主动控制来改善客观地板系统的动态特性。在本研究中，通过电磁质点致动器对结构施加控制力。数字实现了一种带有简单命令限制器的并置速度反馈算法。由于观察到了显著的改进，计划继续研究该解决方案，以修复地板系统，以消除不可接受的居住者引起的地板振动。三个主要目标：1.改进的地板振动控制执行器和算法。2.受人员活动影响的楼层行为模拟。3.多执行器主动控制的实验实现。

9503369 Hanagan Excessive floor vibrations are not uncommon in many types of building structures. Previous research conducted at Virginia Polytechnic Institute & State University has utilized active control to improve the dynamic characteristics of an objectional floor system. In this research, control forces were imparted on the structure, by means of an electromagnetic proof-mass actuator. A collocated velocity feedback algorithm with a simple command limiter was implemented digitally. Due to the significant improvements that were observed, continued research is planned for this solution for repairing floor systems will unacceptable levels of occupant induced floor vibrations. Three main objectives: 1. Improved Actuators and Algorithms for Floor Vibration Control. 2. Simulation of Floor Behavior Subject to Occupant Activities. 3. Experimental Implementation of Active Control Using Multiple Actuators.
