摘要

针对最新提出的智能隔震结构Benchmark模型,阐述了其在考虑横向-扭转耦联振动和双向地震激励下的运动方程,讨论了序列最优算法较之其它几种经典最优算法的改进之处.运用序列最优算法对智能隔震结构Bench-mark模型进行振动控制,并将其和采用LQG算法的控制效果进行了分析比较,结果表明序列最优算法优于LQG算法.
Aimed at the latest smart base isolated Benchmark building,the dynamic equations of motion of the building were derived considering transverse-torsional coupling and bidirectional earthquake excitation.Compared to traditional optimal control algorithm,the advantages of sequential optimal control(SOC) algorithm were analyzed.The algorithm of SOC was also adopted in vibration control with smart base isolated Benchmark model,and the control effects of SOC and LQG were analyzed and compared.The results showed that the SOC algorithm is superior to LQG control algorithm.
