摘　　要：基于经典线性二次最优控制算法(LQR),对安装主动调频气压液柱阻尼器(Active TunedLiquid Column Gas Damper,ATLCGD)的非对称结构进行抗震性能研究。ATLCGD由调频气压液柱阻尼器(Tuned Liquid Column Gas Damper,TLCGD)发展而来,在TLCGD液柱端部连接气压控制箱,通过引入控制气压对结构实施主动控制。以4层非对称结构为算例,利用LQR算法控制结构在ElCentro地震波作用下的振动,ATLCGD对非对称结构抵抗平移-扭转耦联振动有显著的减振效果。Based on classic linear quadratic regulator（LQR） algorithm,the seismic behavior of plan-assymetric buildings installed Active Tuned Liquid Column Gas Damper（ATLCGD） is studied.ATLCGD develops from Tuned Liquid Column Gas Damper（TLCGD）,using a pressurised reservoir at the end of liquid column of TLCGD.Additionaly,the active behavior is obtained by adjusting the pressure in the gas（air） chamber.To calculate example of four-storey assymetric structure,LQR algorithm is applied in controlling the vibration of the structure under El Centro wave,numerical simulations indicate a significant vibration reduction of plan-asymmetric buildings by applying ATLCGD.
