Energy harvesting of nonlinear damping system under time delayed feedback gain

Energy harvesting of nonlinear damping system under time delayed feedback gain

This paper presents the application of delayed feedback velocity for optimizing the harvested power in cubic nonlinear damper system. We consider a harvester consisting of a nonlinear single degree of freedom system (spring-masse-damper) subjected to a base excitation near the primary resonance. Ana...
