Abstract
This paper presented the development and real-time control of a magnetostrictive micro actuator. Magnetostrictive material has many advantages such as high response time, precision displacement and powerful output force. But Magnetostrictive material has characteristic of hysteresis. Conventional Preisach model which based on experimental data is not suitable to the real-time control because of controlling a magnetostrictive system by Preisach model costs a lot of calculating time. And, we prove the validity of proposed model through the experimental comparison between the classical Preisach model and the proposed one.
