title = "Vibration-based energy harvesting circuit using feed-forward control",
abstract = "This paper proposes an improved electromagnetic damper cum energy harvester (EMDEH), consisting of an electromagnetic damper and a specially designed energy harvesting circuit (EHC). EMDEH is intended to suppress structural vibrations by harvesting vibration energy of structures. A microcontroller unit (MCU) is applied in the EHC to control the power switch by adjusting the duty cycle appropriately through a feed-forward control. Consequently, the EHC can achieve a controllable equivalent damping coefficient. The performance of the proposed EHC was validated through a cyclic test on a universal testing machine. Although the total energy conversion is relatively low, a desirable constant resistance feature could be achieved and an electrical power with hundreds of mWs could be charged into a battery. These experimental results revealed the benefit of using MCU in a feed-forward control system in EMDEH, and the improved EMDEH could fulfill dual-functions, namely, simultaneous vibration control and energy harvesting, with an improved performance.",
