    On-chip spectral analysis with low power and optimal Control for energy harvesting using piezoelectric devices
    (2018-10-22) Monte, Gustavo; Marasco, Damian; Garcia, Andes; Perotti, Emanuel
    This paper presents a low power DC-DC buckboost topology functioning battery-less on the basis of a novel technique using a combination of both: singular optimal control plus an analog circuit control law. The very low power consumptions along with the optimal energy harvested, makes possible to perform FFT calculations on-line and on-chip for vibration analysis applied to wind-turbines maintenance operation using an ST microcontroller and transmitting up to 500 m. The complete functioning circuit is shown along with real measurements.
