Maximization of the electrical power generated by a piezo-magneto-elastic energy harvesting device

João Victor Ligier Lopes Peterson, Vinicius Gonçalves Lopes, Americo Cunha Jr

Resumo


This work deals with the maximization of the mean power in a piezoelectric energy harvesting device. The voltages are acquired by applying different force amplitudes and initial positions for the system. These signals are treated in order to identify and separate chaotic from regular (non chaotic) results, through 0-1 test for chaos. An optimization problem is numerically solved in order to identify an optimal configuration of parameters.


Palavras-chave


Nonlinear dynamics, energy harvesting, chaos, optimization, test 0-1 for chaos.
