      abstract     = {Scanning quantum dot microscopy is a recently developed
                      high-resolution microscopy technique that is based on atomic
                      force microscopy and is capable of imaging the electrostatic
                      potential of nanostructures like molecules or single atoms.
                      Recently, it could be shown that it not only yields
                      qualitatively but also quantitatively cutting edge images
                      even on an atomic level. In this paper we present how
                      control is a key enabling element to this. The developed
                      control approach consists of a two-degree-of-freedom control
                      framework that comprises a feedforward and a feedback part.
                      For the latter we design two tailored feedback controllers.
                      The feedforward part generates a reference for the current
                      scanned line based on the previously scanned one. We discuss
                      in detail various aspects of the presented control approach
                      and its implications for scanning quantum dot microscopy. We
                      evaluate the influence of the feedforward part and compare
                      the two proposed feedback controllers. The proposed control
                      algorithms speed up scanning quantum dot microscopy by more
                      than a magnitude and enable to scan large sample areas.},
