半主动控制系统在保护结构免受强地震和大风等自然灾害方面受到了相当大的关注，因为它们不仅提供了被动控制系统的可靠性，而且还保持了全主动控制系统的多功能性和适应性。在许多半主动控制装置中，磁流变（MR）流体阻尼器是一个特别有前途的类别。在土木工程领域，自20世纪90年代中期这种独特的半主动装置首次引入土木工程应用以来，已经对基于磁流变液阻尼器的控制系统进行了大量研究和开发。2001年，MR流体阻尼器首次应用于全尺寸在役土木工程结构。这篇最新的论文包括详细的文献综述磁流变液阻尼器的动态模型，以描述其复杂的动态行为和考虑磁流变液阻尼器特性的控制算法。这篇广泛的综述为使用MR流体阻尼器的半主动控制系统提供了参考。基于磁流变阻尼器的半主动控制系统具有减轻全尺寸土木工程结构在自然灾害下的响应的潜力。
Semiactive control systems have received considerable attention for protecting structures against natural hazards such as strong earthquakes and high winds, because they not only offer the reliability of passive control systems but also maintain the versatility and adaptability of fully active control systems. Among the many semiactive control devices, magnetorheological (MR) fluid dampers comprise one particularly promising class. In the field of civil engineering, much research and development on MR fluid damper-based control systems has been conducted since this unique semiactive device was first introduced to civil engineering applications in mid 1990s. In 2001, MR fluid dampers were applied to the full-scale in-service civil engineering structures for the first time. This state-of-the-art paper includes a detailed literature review of dynamic models of MR fluid dampers for describing their complex dynamic behavior and control algorithms considering the characteristics of MR fluid dampers. This extensive review provides references to semiactive control systems using MR fluid dampers. The MR fluid damper-based semiactive control systems are shown to have the potential for mitigating the responses of full-scale civil engineering structures under natural hazards.
