半主动TLCD对偏心结构的离散模糊变结构控制
|
摘要
采用在结构水平双向设置TLCD半主动控制装置的方法,对偏心结构在多维地震作用下的离散模糊变结构控制问题进行了研究。首先建立了结构-TLCD扭转耦联控制系统微分方程及其离散化状态空间表达,然后阐述了基于模糊逻辑的变结构控制的基本策略,最后应用该模糊变结构控制策略对一个五层偏心结构的TL-CD半主动控制问题进行了仿真分析。仿真分析的结果表明,该方法在对结构的平动反应和扭转反应都能起到较好的减震效果的同时,还具有对结构固有参数不确定性的较强的鲁棒性。
In this paper,a semi-actively tuned liquid column damper(TLCD) based on discrete-time fuzzy variable structure law is proposed to vibration control of eccentric buildings excited by multi-dimensional earthquake ground motions.Firstly,tThe numerical model of a multi-story eccentric building-TLCD system is given and its continuous state equation is set up and discretized.And then,the theory of fuzzy variable structure control(FVSC) is simply discussed and the semi-active control strategy is established and implemented by FVSC.The numerical simulated example has shown that it is an effective method for controlling the translational response and rotational response of the eccentric buildings,furthermore,the proposed control method possesses better robustness to uncertainty of structure parameters.
