A system employing a resonating device and a controller implements a method involving an establishment by the controller of open-loop oscillations of the resonating device at a resonating frequency of the resonating device, and an establishment by the controller of closed-loop oscillations of the resonating device based on the open-loop oscillations of the resonating device at the resonating frequency. To this end, the controller controls an application and a tuning of a first open-loop drive signal to the resonating device based on a design-drive standard resonating frequency range whereby the controller can measure and designate a frequency of a resonating output signal from the resonating device as a calibration resonant frequency, and controls an application and a tuning of a second open-loop drive signal to the resonating device based on the calibration resonant frequency whereby the controller can subsequently apply a closed-loop drive signal to the resonating device.
