提出了一种闭环全反馈控制算法，用于使用主动调谐质量阻尼器 (ATMD) 对建模为单自由度 (SDOF) 系统的建筑物进行控制。控制力是根据 SDOF 系统和主动质量阻尼器的加速度、速度和位移反馈计算得出的。被动控制装置的属性，包括调谐质量阻尼器的刚度和阻尼常数以及执行器的三个增益系数，是通过最小化单自由度系统的位移方差而导出的。进行仿真以评估主动调谐质量阻尼器设计在 SDOF 系统和 10 层三开间建筑框架示例上的性能。结果表明，基于速度反馈的 ATMD 的控制效率取决于假设的无源控制装置特性。此外，采用完整反馈的具有最佳被动特性的 ATMD 可以进一步减少结构位移。结果还表明...
A closed-loop complete-feedback control algorithm is proposed for the control of a building modeled as a single-degree-of-freedom (SDOF) system using an active tuned mass damper (ATMD). The control force is calculated from the acceleration, velocity, and displacement feedbacks of the SDOF system and the active mass damper. The passive-control-device properties, including the stiffness and damping constants of the tuned mass damper and the three gain coefficients of the actuator, are derived by minimizing the displacement variance of the SDOF system. Simulations are performed to evaluate the performance of the active-tuned-mass-damper design on the examples of a SDOF system and a 10-story three-bay building frame. The results show that the control efficiency of the ATMD based on velocity feedback depends on the passive-control-device properties assumed. Also, the ATMD with optimal passive properties using complete feedback results in further reduction in the structural displacement. The results also show t...
