High power demand of active structural control systems in tall buildings and incapability of energy storage system (ESS) in supplying the demanded power results in a power shortage which, in turn, can adversely affect their performance. Energy regeneration in active structural control systems may contribute to efficient energy management and sustainable power supply in these systems. This paper explores various aspects of energy regeneration of active pendulum system (APS) in tall buildings. A regenerative hybrid passive-active pendulum system (HPAPS) is proposed to control the wind-induced vibrations in a benchmark tall building. The vibration control system includes an APS that incorporates a fuzzy logic controller (FLC) to calculate the stabilizing torque. The regeneration system comprises an energy management system (EMS), DC-DC convertor, AC boost rectifier, ESS, and their corresponding controllers which have been carefully modeled and included in the simulations. Furthermore, the system is implemented in a laboratory-scale structure, and extensive shake table tests are carried out to examine the system’s performance in the presence of seismic disturbances. The findings of this research are as follows: the proposed APS can well reduce the transmitted vibrations to the structure; the top story’s displacements and accelerations are reduced by 47 and 50 percent respectively in the benchmark model, implying the effectiveness of the active structural control system in enhancing simultaneous structural safety and inhabitants’ comfort. Moreover, the energy regeneration scheme can restore 34 percent of the APS’s power. Experimental results also verify the simulation results where a considerable drop in both the top story’s displacement and acceleration is reported for the test structure under seismic load. Furthermore, 44 percent of the active pendulum power is restored in the battery of the laboratory-scale APS.
