ATLCD 由调频液柱阻尼器（Tuned Liquid Column Damper，TLCD）发展而来，在 TLCD 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。采用被动 TLCD 优化设计方法设计阻尼比及频率比，采用 LQR 算法确定 ATLCD 系统的主动控制力，并对 LQR 算法中权矩阵采用遗传算法进行优化。以一五层钢框架结构为例，顶层装 ATL-CD 用 LQR 算法进行主动控制，加载 El －Centro 地震波进行时程响应分析，比较无控结构及被、主动控制结构的时程响应结果表明，采用 ATLCD 的减振效果明显优于采用被动装置。

Active tuned liquid column damper (ATLCD),developed from the tuned liquid column damper (TLCD),is based on the adjuctment of pressure in a gas chamber at the end of the liquid column by virtue of a pressurized reservoir.In the design of ATLCD,the Q and S matrices were obtained by using genetic algorithm.The control performance of ATLCD used in multiple degrees of freedom system was verified via the example of a five-story structure subjected to earthquake excitation.The results indicate that the ATLCD installed in high-rise building can achieve significant response reduction in comparison with the passive TLCD.
