    • Design of a nonlinear damping control scheme for nanopositioning 

      Vagia, Marialena; Eielsen, Arnfinn Aas; Gravdahl, Jan Tommy; Pettersen, Kristin Ytterstad (Journal article; Peer reviewed, 2013)
      The application of a nonlinear control law for vibration damping on a typical nanopositioning system is investigated. The nonlinear control law is an augmentation of the linear integral force feedback scheme, where the ...

    • Higher-Harmonic AFM Imaging with a High-Bandwidth Multifrequency Lyapunov Filter 

      Harcombe, David M.; Ruppert, Michael G.; Ragazzon, Michael Remo Palmén; Fleming, Andrew J. (Journal article; Peer reviewed, 2017)
      A major difficulty in multifrequency atomic force microscopy (MF-AFM) is the accurate estimation of amplitude and phase at multiple frequencies for both z-axis feedback and material contrast imaging. A lock-in amplifier ...
