The purpose of this paper is to apply self-tuning fuzzy robust control for structurally controlling buildings with sliding bearing isolation. Combining fuzzy control and robust control such as sliding mode control reduces fuzzy rule bases complexity and ensures stability and robustness. Lyapunov theory is used to develop a self-tuning law. Stiffness uncertainty and time delay is utilized to demonstrate the robustness of this proposed algorithm. The effectiveness of this algorithm is demonstrated by simulation results for the Taiwan Chi Chi earthquake in 1999. Simulations show that self-tuning fuzzy robust control achieves satisfactory results in the application of structural control for buildings with sliding bearing isolators.
