| 摘 要： | 本文针对结构参数非匹配不确定性问题,采用简化滑动模态控制方法．即在滑动面的没计中忽略非匹配不确定性的影响,对一个顶层放置AMD系统的五层弹塑性建筑结构进行了主动控制数值分析．考虑了结构层屈服位移的不确定,数值模拟结果表明,简化方法具有很强的鲁棒性,结构参数相对于期望值的变化幅度为-40％至40%时．简化方法均有很好的控制效果。

| Abstract: | A simplified sliding mode control algorithm is*2introduced to control the vibration of structures with parametric unmatched uncertainty. The algorithm is applied to control the vibration of a 5-story structure with active tuned mass damper (AMD) induced by earthquake. The controller is designed by the open-closed-loop method. The uncertainty (yielding displacement) of structural story is considered. The results of numerical analysis show the strong robustness of the simplified SMC algorithm. The structural responses are effectivelycontrolled when the variety of structural parameters ranges from -40% to 40% corresponding mean values. |
