| 摘 要： | MR阻尼器是一种性能优良的半主动控制装置，已广泛应用于结构振动控制领域。本文针对MR阻尼器控制系统的特点，提出了一种基于遗传算法的模糊控制器设计方法，对地震作用下的建筑结构实施模糊控制。该方法将多目标遗传算法NSGA—II和模糊控制技术相结合，人工设计基本模糊控制器，以位移、层间位移和绝对加速度为控制目标，利用NSGA—II来优化生成最优的模糊控制规则。一个3层结构的仿真结果表明。所设计的模糊控制器在四种不同的地震波作用下均能有效地减小结构的地震反应，控制效果明显优于被动控制，与Clipped-LQR控制效果接近。

| Abstract: | MR dampers are a new class of semi -active control devices which have many attractive features and have been widely used instructure control. A strategy based on genetic algorithm (GA) to design fuzzy controller of MR dampers was presented here. This strategy combine theMulti-Objective GA-NSGA-II and fuzzy control technique. NSGA-II was employed to design and optimize the fuzzy rules. A 3-story frame structureequipped with MR dampers on the first floor is investigated. El Centrol earthquake, Kobe earthequak... |
