Abstract
A method of damping control for a nanomechanical test system, the method including providing an input signal, providing an output signal representative of movement of a displaceable probe along an axis in response to the input signal, performing a frequency-dependent phase shift of the output signal to provide a phase-shifted signal, adjusting the phase-shifted signal by a gain value to provide a feedback signal, and adjusting the input signal by incorporating the feedback signal with the input signal.
