• Adaptive feed-forward hysteresis compensation for piezoelectric actuators 

      Eielsen, Arnfinn Aas; Gravdahl, Jan Tommy; Pettersen, Kristin Ytterstad (Journal article; Peer reviewed, 2012)
      Piezoelectric actuators are often employed for high-resolution positioning tasks. Hysteresis and creep nonlinearities inherent in such actuators deteriorate positioning accuracy. An online adaptive nonlinear hysteresis ...
