We examine a vibrational energy harvester consisting of a mechanical resonator
with a fractional damping and electrical circuit coupled by a piezoelectric converter.
By comparing the bifurcation diagrams and the power output we show that the
fractional order of damping changes the system response considerably and effects
the power output. Various dynamic responses of the energy harvester are examined
using phase trajectory, Fourier spectrum, Multiscale Entropy and 0-1 test. The
numerical analysis shows that the fractionally damped energy harvesting system
exhibits chaos, and periodic motion, as the fractional order changes. The observed
bifurcations strongly influence the power output. |
