Abstract
A system includes a power driver, configured to generate an electric excitation; an oscillating system, configured to perform an oscillation induced by the electric excitation; a feedback detector, configured to detect a feedback measurement signal with to the oscillation; and a controller configured to operate: in a closed loop mode, to control the power driver to generate the electric excitation as a discontinuous electric excitation according to timing information obtained from the detected feedback measurement signal, to synchronize the discontinuous electric excitation with the detected feedback measurement signal; in a learning mode preceding the closed loop mode, to control the power driver to generate the electric excitation as a continuous electric excitation, to obtain timing information from the feedback measurement signal to be used, at least once, in the subsequent closed loop mode, to synchronize the discontinuous electric excitation with the detected feedback measurement signal.
