Abstract: Aiming to the magnetic hysteresis non-linear problems of giant magnetostrictive actuator existing in the working process, a mathematical model describing output displacement of the giant magnetostrictive precise actuator which is used in the field of precision and ultra-precision drive is built. Moreover, a mathematical method for solving the inverse model is proposed. In this method, displacement mean magnetic hysteresis line is used as current calculation reference value, and iteration step size is adjusted according to the deviation between output displacement and target real-timely. The model and solving method of inverse model can realise a stable control for actuator's output displacement. The average relative error of displacement tracking is about 1.13%. The achievements will provide an effective way for the application of giant magnetostrictive actuator in the field of precision and ultra-precision machining.
