In this paper, a smart structure is developed by integrating a semi-active control strategy with an online synchronization-based damage detection method. In this algorithm, the structural damages are identified in real-time with the synchronization-based method using displacement and velocity measurements of the structure. Then, a fuzzy logic controller is applied for determination of the control forces according to the occurrence of damages. A five-story linear shear building equipped with magneto-rheological (MR) dampers is studied numerically to verify the performance and efficiency of the proposed integrated method for both damage detection and vibration suppression. One damage scenario and four earthquake records are used for such purpose. Results demonstrate that the proposed algorithm has the capability of identifying structural damages satisfactorily while exerting suitable control forces to compensate for the damages occurrence and mitigating the dynamic responses of the structure. Furthermore, it is shown that in comparison with the long-established method of only vibration control, the total energy consumption is significantly reduced, an issue of concern in optimal control of structures.

使用同步和半主动控制的结构的同时在线损伤检测和振动控制

在本文中，通过将半主动控制策略与基于在线同步的损伤检测方法相结合，开发了一种智能结构。在该算法中，使用基于同步的方法使用结构的位移和速度测量来实时识别结构损伤。然后，应用模糊逻辑控制器根据损坏的发生确定控制力。对配备磁流变 (MR) 阻尼器的五层线性剪切建筑进行了数值研究，以验证所提出的损伤检测和振动抑制综合方法的性能和效率。为此目的使用了一种破坏情景和四次地震记录。结果表明，所提出的算法能够令人满意地识别结构损伤，同时施加适当的控制力来补偿损伤的发生并减轻结构的动力响应。此外，结果表明，与长期以来的仅振动控制方法相比，总能耗显着降低，这是结构优化控制中关注的问题。
