近年来土木工程结构上采用的主动调谐质量阻尼(ATMD)控制系统开始引起研究者们极大的关注。强调利用遗传法和模糊逻辑(GFLC)的组合作用,在ATMD控制系统的设计和优化措施中选择合适的参数,以使得在地震激励作用下建筑的反应最小化。因此,提出的方法,在处理不可预知的非线性现象方面,具有模糊逻辑控制(FLC)和遗传法(GAs)的双重优势。模型采用剪切型框架,并且在状态空间下解决问题。这种方法被应用在位于伊朗共和国的雷什特城的一个11层高的实际建筑上。从这种控制系统中得到的结果,与采用TMD方案和线性二次调节(LQR)控制方法中得出的结果相对比发现,GAs和FLC的综合使用对减少建筑在地震作用下的反应非常有效。
In recent years, the active tuned mass damping (ATMD) control system adopted in civil engineering has begun to attract the great attention of researchers. The combination of genetic method and fuzzy logic (GFLC) is emphasized to select appropriate parameters in the design and optimization of ATMD control system so that the response of the building under seismic excitation is minimized. Therefore, the proposed method has the dual advantages of fuzzy logic control (FLC) and genetic method (GAs) in dealing with unpredictable nonlinear phenomena. The model uses a shear frame and solves the problem in the state space. This method is applied to a real 11-storey building in Reith-i-City, Republic of Iran. The results obtained from this control system show that the combined use of GAs and FLC is very effective in reducing the response of buildings to earthquakes, as opposed to using the TMD approach and the linear quadratic regularization (LQR) control approach .
