Paper Title:
Study on Bilinear Interpolation Preisach Model of Piezoelectric Actuator
  Abstract

Piezoelectric actuator is being widely used in precision positioning technology for its high resolution of displacement, high stiffness and fast frequency response. However, its hysteresis nonlinearity limited its control accuracy. The key way to eliminate this limitation is to describe the nonlinearity. Aiming at the inaccuracy of Preisach model, the characteristic of piezoelectric actuator was introduced, and its static hysteresis were studied by experiment. Then bilinear interpolation was introduced to calculate the Preisach model prediction which was not located in the experiment table, and a bilinear interpolation Preisach hybrid model was proposed. The experiment results revealed the proposed Preisach hybrid model to be an accurate one.
