摘要本文旨在研究主动控制惯性基结构控制装置的有效性。作为一个例子，调谐惯性质量电磁传感器（TIMET）组成的惯性，调谐弹簧，和电机，和性能时，电机主动控制进行了评估。此外，在地震事件期间由电机产生和消耗的能量进行了检查，并讨论了自供电控制方案的可行性。对基准三层建筑进行的数值研究表明，主动控制的TIMET比被动系统工作得更好，并且自供电系统是高度可行的。
ABSTRACT This paper aims to investigate the effectiveness of actively controlled inerter-based structural control devices. As an example, a tuned inertial mass electromagnetic transducer (TIMET) consisting of an inerter, a tuning spring, and a motor is employed, and the performance when the motor is controlled actively is evaluated. Moreover, the energy generated and consumed by the motor during seismic events is examined, and the feasibility of the self-powered control scheme is discussed as well. Numerical studies carried out on the benchmark three-story building show that actively -controlled TIMETs work better than the passive system and that the self-powered system is highly feasible.
