结合自校正控制、模糊逻辑和迭代学习控制的基本思想,提出采用自整定模糊控制确定迭代学习律的方法,提高了迭代学习控制的鲁棒性。选取建筑结构振动控制Benchmark第二阶段的地震作用Benchmark模型作为研究对象,进行模糊迭代学习控制地震响应仿真计算,结果表明该方法能够对Benchmark模型的地震响应进行有效控制,而且具有学习控制律简单实用、跟踪精度高、鲁棒性强等优点。

With research into the fundamental ideas of self-tuning control,fuzzy logic and iterative learning control（ILC）,this paper provides a new type of fuzzy iterative learning control strategy to reduce the seismic response of tall building.It improves the robustness of the iterative learning control.The model of a seismically excited building in the second generation benchmark vibration control for buildings is studied,using the new control strategy to calculate the seismic response of the building.The result of simulation shows that fuzzy iterative learning control strategy can control the seismic response of the building effectively,and has advantages of simple and practical learning control law,high precision in trajectory and good robustness.
