摘要

以含主动控制系统的框架结构为研究对象,根据振动控制理论和线性二次型(LQR)最优控制算法,建立仿真模型,推导系统微分运动方程,确定控制系统参数,设计控制力,研究建筑结构减震情况。以一栋8层框架结构为仿真实例,计算结果表明,本文方法减震效果良好。
The paper uses frame structure with active control system as the research object,establishes the simulation model based on the theory of vibration control and the optimal control algorithm of linear quadratic(LQR),obtains the motion equation,determines the parameters and control force in the control system and studies the anti-vibration in the building.Finally,it uses an 8 storey building as case for simulation and concludes that the anti-seismic effect of the proposed method is very well.
