Abstract

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.
