This research investigates the performance of actively-controlled tuned inertial electromagnetic transducers (TIMETs) and discusses the feasibility of the self-powered control scheme for the TIMETs as well. The TIMET consists of an inerter, a tuning spring, and a motor and can absorb kinetic energy effectively by taking advantage of the resonance effect of the inerter and convert it to electrical energy by the motor. So far, various kinds of inerter-based devices have been proposed; however, most of these devices are limited to passive or semi-active control strategies. Therefore, to investigate the effectiveness of the actively-controlled TIMETs, linear quadratic Gaussian (LQG)-based acceleration feedback control strategies are applied to a three-story benchmark building model with the TIMETs. In addition, the feasibility of the self-powered control scheme utilizing the absorbed energy is discussed by calculating the absorbed and injected energies. Numerical simulation studies show that the actively-controlled TIMETs work better than the passive system and that the self-powered system is feasible, depending upon the control forces, the energy conversion rate of a motor.
