The active tuned mass damper (ATMD) is a reliable energy-dissipating device to effectively protect structures from serious damages due to earthquake excitations. This study proposes the optimal design of sliding sector control (SSC) for the seismic protection of an 11-story shear building structure equipped with ATMD. First, the SSC controller is optimally designed for the seismic control of the structure subjected to an artificial earthquake. Then, the effectiveness of the optimized SSC (OSSC) is assessed in reducing the seismic responses of the structure subjected to four near- and far-fault earthquake excitations. The efficient performance of the OSSC technique is also validated and compared with that of a number of the control techniques such as linear quadratic regulator (LQR), fuzzy logic control (FLC), proportional-integral-derivative (PID), and optimal sliding mode control (OSMC). Comparative results demonstrate the efficiency and robustness of the proposed OSSC in comparison with those of the other controllers.

基于优化的结构主动抗震滑动扇区控制设计

主动调谐质量阻尼器（ATMD）是一种可靠的耗能装置，可有效保护结构免受地震激励造成的严重损坏。本研究提出了滑动扇区控制 (SSC) 的优化设计，用于配备 ATMD 的 11 层剪力建筑结构的地震防护。首先，SSC控制器针对人工地震结构的地震控制进行了优化设计。然后，评估优化的 SSC (OSSC) 在降低结构在四种近断层和远断层地震激励下的地震响应方面的有效性。OSSC 技术的高效性能也得到了验证，并与线性二次调节器 (LQR)、模糊逻辑控制 (FLC)、比例积分微分 (PID) 和最优滑模等多种控制技术进行了比较控制（OSMC）。比较结果证明了所提出的 OSSC 与其他控制器相比的效率和鲁棒性。
