摘要：AbstractAdvent of low-powered, wireless and miniature sensors with semi-conductor revolution necessitated innovation in energy supply and solutions. One such innovation is using ambient energy to power sensors with little power requirement. This study analyses the potential of a bi-stable nonlinear harvester for possible broadband energy harvesting with sufficient power output. An inverted cantilever beam with tip mass that shows chaotic vibrations is analysed. In this paper, a time-delayed feedback control is used to stabilize this system into the unstable periodic orbits (UPOs) embedded inside chaotic attractor. Two situations are considered to compare; (a) the system dynamics without power harvesting mechanism and (b) with power harvesting feature. Focus is upon the capability of enhancing the efficiency of the harvester using feedback and finally effect of control parameters on the dynamics of the system is reported.
