摘要

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。将多目标遗传算法NSGA-II和模糊控制技术相结合,利用NSGA-II来生成最优的模糊控制规则,并通过一个2层偏心结构的仿真分析,证明了该方法的有效性。
MR dampers are a new class of semi-active control devices which have many attractive features and have been widely used in structure control. A strategy based on genetic algorithm (GA) to design fuzzy controller of MR dampers is presented. This strategy combines the Multi -Objective GA NSGA-II and fuzzy control technology. NSGA-II is employed to design and optimize the fuzzy rules. The effectiveness of this strategy is proved by a stimulation analysis of a 2-story asymmetric structure equipped with MR dampers on the first floor.
