Exact H2 Optimal Tuning and Experimental Verification of Energy-Harvesting Series Electromagnetic Tuned-Mass Dampers

“…Then, the corresponding optimal mechanical and electrical elements can be similarly obtained using Eqs. (21) and (22).…”

“…On the other hand, large amounts of associated vibration energy are converted to waste heat by the aforementioned mechanical TMDs and are worth being harvested to provide sustainable energy for many applications in civil structures. In order to enhance vibration mitigation performance and harvest the wasted energy, a new type of TMDs, energy-harvesting EMTMDs, has been proposed in the past decade [12][13][14][15][16][17][18][19][20][21]. The idea is to use an electromagnetic transducer to harvest the energy from structural vibration while producing a resisting electromagnetic force to dampen the vibration of the primary structure, acting as an electromagnetic damper as well as an energy harvester.…”
