Abstract
This paper applies adaptive fuzzy sliding mode control of structural control for bridges. Combining fuzzy control and sliding mode control can reduce the complexity of fuzzy rule base. It also ensures stability and robustness. The Lyapunov theory is used to develop adaptive law. adaptive sliding mode control is applied to 3 types of bridge, with LRB (Lead Rubber Bearing), sliding bearing isolators and no isolation device. The condition of stiffness uncertainty and time delay is used to show the robustness of this algorithm. The effectiveness of this algorithm is demonstrated by simulation results for a long period and a wide-pass white noise artificial earthquake. All these simulations are shown that adaptive sliding mode control can achieve satisfactory results in the application of structural control for bridges.
