Abstract

This paper presents the mathematical analysis and parameter determination of feedback control system for a scanning tunneling microscope. We can obtain the frequency characteristics and transient response of a STM assembly for a tube scanner by its response to sine wave and square wave stimuli. In this way the optimum feedback parameters for the critically damped response can be determined. The design of the appropriate control electronics of a practical instrument is described too.
