Abstract

This paper analyzes the performances of an embedded closed-loop control system with a compensated magnetostrictive actuator (e.g., a Terfenol-D based device) for micropositioning tasks. The control system and the compensation algorithm are implemented, as a standalone application, on a microcontroller. The embedded application and its performance in terms of tracking error reduction is evaluated with respect to both open and closed loop configurations. The uncompensated case is used as a reference
