Abstract
An atomic force microscope (AFM) comprises a physical system and a controller comprising a plurality of digital filters and configured to control the physical system. The AFM is tuned by performing automatic loop shaping on a loop response defined by a frequency response of the physical system and a frequency response of the controller, and adjusting a gain of the controller according to a peak in a magnitude of the loop response.
