摘要

基于线性矩阵不等式,给出了递阶分散的鲁棒控制设计方法,以解决不确定建筑结构的振动控制问题.通过悬臂梁的振动试验,设计了基于Matlab/xPC的实时振动控制系统,利用压电智能材料实现了悬臂梁半物理实时数据采集与控制试验.试验结果表明,当结构的质量发生变化时,递阶分散控制方法能很好地对结构振动进行控制.时域分析表明,结构衰减速度随着与振源距离的增大而显著加快.试验证明了递阶分散鲁棒控制方法对不确定结构振动控制的可行性和有效性.

Hierarchical Decentralized Robust Control Method of Uncertainty Structure Vibration

Abstract:

Based on the linear matrix inequality,a hierarchical decentralized state-feedback controller was given to resolve the vibration control of an uncertainty building structure.Active control experiments were constructed by a Matlab/xPC real-time control system,and half physical real-time data acquisition and control of a cantilever beam were realized by using piezoelectric materials,showing a favorable performance even if when the mass of a structure changes.The time domain analysis indicates that the vibration attenuates quickly with the increase of a distance away from the vibration source.The experimental result shows that the controller can work very well,and this method has strong robustness.
