Active Control of Floor Vibration

在许多类型的建筑结构中，过度的地板振动并不罕见。弗吉尼亚理工学院和州立大学先前的研究利用主动控制来改善目标地板系统的动态特性。在本研究中，通过电磁证明质量执行器将控制力传递给结构。以数字方式实现了一种带有简单指令限制器的并行速度反馈算法。由于观察到的显著改进，计划继续研究这种解决方案，以修复地板系统，使其达到不可接受的水平，从而避免乘客引起的地板振动。三个主要目标：楼板振动控制的改进致动器和算法。受居住者活动影响的地板行为模拟。多作动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.
