电磁驱动AMD系统控制结构地震响应的振动台试验
|
摘要
本文在此前一系列有关新型电磁驱动AMD控制系统力学建模、性能试验和控制策略研究的基础上,进行了结构地震响应控制的小型振动台试验研究。首先,针对配置了电磁驱动AMD控制系统的Quanser标准两层剪切型框架结构模型,建立了无控计算模型,通过正弦扫频试验验证了模型参数,从而为结构振动主动控制试验研究提供了准确的被控对象模型;其次,设计了电磁驱动AMD控制系统基于极点配置控制算法的试验控制策略和状态观测器,通过数值分析验证了状态观测器估计结果的准确性;最后,在完成以上各项准备工作的基础上,分别对结构输入了典型Benchm ark标准地震动,进行振动台试验,试验结果表明电磁驱动AMD控制系统对结构的地震响应具有显著的控制效果,验证了该新型系统应用于结构振动控制的有效性和可行性。
Based on the previous theoretical modeling,series dynamical tests and control strategies of the innovative electromagnetic mass damper(EMD) control system,the shaking table tests of the structural seismic response control using EMD were studied in this paper.Firstly,two uncontrolled models of the experimental structure,the standard two-floor shearing structure,with the EMD system installed on the top floor were proposed,and the parameters of the structural models were validated through sine sweep tests,and an accurate uncontrolled model for structural vibration control study was prepared.Then,active control strategies as well as state observers were designed using the pole assignment algorithm,afterwards the observing accuracy was verified through simulation comparisons.At last,after fulfilling the above preparations,a series of benchmark earthquake waves were input onto the specimen by the shaking table,and the test results show that the EMD system has a remarkable ability of suppressing the structural vibrations.
