| Summary: | 博士 === 國立中央大學 === 土木工程研究所 === 88 === The purpose of the research is to apply adaptive fuzzy sliding mode control of structural control for bridges and base-isolated buildings. Combining the fuzzy control and sliding mode control one can reduce the complexity of fuzzy rule base. It also ensures the stability and robustness. The Lyapunov theory is used to develop the adaptive law. In addition to full-state-feedback controller, an output feedback algorithm using only the measured information from a few sensors is presented. Finally, the adaptive fuzzy sliding mode control is applied to three types of bridge, no isolator, with LRB, and sliding bearing isolators. It is also used to two types of base-isolated building, with LRB, and sliding bearing isolators. The condition of the stiffness uncertainty and time delay is utilized to illustrate the robustness of this algorithm. The effectiveness of this algorithm is demonstrated by simulation results for a long period, a wide-pass white noise artificial earthquake and Taiwan Chi Chi earthquake occurred in 1999. All these simulations are shown that adaptive fuzzy sliding mode control can achieve satisfactory results in the application of structural control for bridges and base-isolated buildings
