Abstract

A power source is configured to apply a first alternating electric excitation signal to an oscillation blade device at a first excitation frequency causing a blade of the oscillation blade device to oscillate at a first oscillation frequency. A current detector is configured to measure amplitude values of the current supplied by the power source to the oscillation blade device. A processor is configured to assess a plurality of successive peak values of the measured amplitudes, determine a second oscillation frequency for the blade if variation in the successive peak values is detected and send a command to the power source to apply a second alternating electric excitation signal to the oscillation blade device at a second excitation frequency which matches the determined second oscillation frequency.
