中文摘要：

文章将重叠分散控制方法和滑模控制算法相结合，提出了地震作用下高层建筑结构多重叠分散滑模控制方法。基于包含原理，将地震作用下高层建筑结构振动控制系统分解成一系列子系统，针对每个子系统设计分散滑模控制器，通过收缩分散滑模控制器到原状态空间，获得多重叠分散滑模控制器。采用直接驱动方案和层间驱动方案，对某20层Benchmark结构模型进行数值模拟与计算。数值仿真结果表明，重叠分散控制、2次重叠分散控制和多重叠分散控制都获得了与集中控制相近的控制效果，减少了计算成本，增加了控制器设计的灵活性。

英文摘要：

In this paper, combining overlapping decentralized control（ODC） and sliding mode control （SMC）, the multi-overlapping decentralized sliding mode control approach of tall buildings under seismic excitation is established. Based on the inclusion principle, the vibration control system of tall buildings can be decomposed into a set of subsystems under the seismic excitation. The decentralized sliding mode controllers are designed for each of subsystems. The multi-overlapping decentralized sliding mode controllers are obtained by contracting decentralized sliding mode controllers to original state space. The numericalsimulation and calculation of Benchmark structural model of twenty-story building are conducted by using direct actuation and inter-story actuation scheme respectively. The numerical simulation results show that overlapping decentralized control, twice overlapping decentral- ized control and multi-overlapping decentralized control all can achieve similar control effects as cen- tralized control achieves. The computational cost can be reduced and the controller design will become more flexible.
