摘要

基于磁流变阻尼器的结构半主动控制兼有被动和主动控制的优点,近年来受到了广泛的关注,但设计与之相适应的控制系统仍是一项具有挑战性的工作。本文针对多输入多输出结构-阻尼器系统,提出了一种基于遗传算法的模糊控制器设计方法。由遗传算法自适应优化生成模糊控制规则,建立从加速度响应到磁流变阻尼器控制电压之间的关系,对结构进行半主动控制。通过两个结构振动控制实验,证明了该方法的有效性。

Abstract

Recently, semi-active control using megnetorheological (MR) dampers that combines the advantages of both active control and passive control has received considerable attention. However, how to design the corresponding control system is still a challenge task. This study proposes a genetic algorithms-based strategy for designing the fuzzy controller for the multi-input-multi-output (MIMO) structure-MR dampers system. This strategy determines the command voltages of MR dampers from the acceleration responses of the structure. Genetic algorithms are employed to adaptively design and optimize the fuzzy rule bases. The experimental studies have demonstrated the effectiveness and efficiency of the fuzzy control systems based on the proposed design strategy in reducing the responses of a vibrating structure.
