Paper Abstract

This work presents a novel approach of modeling hysteresis using the Preisach model. Instead of relying entirely on the Presisach model, the hysteretic behavior is separated into a non-linear least squares fit function and a Preisach model. This separation allows for the independent analysis of the non-linear portion and hysterestic behavior of actuators. In particular, the paper addresses the response modeling of deformable mirrors (DM) piezoceramic actuators for use in adaptive optics. Several inversion algorithms have also been developed and presented here. These algorithms are used in a feed-forward loop as part of the DM control algorithms.
