| Abstract: | Giant magnetostrictive material (GMM) is a new type of function materials developed in recent years. The micro-displacement actuator based on GMM has large output power and a new level of performance in control precision. In this paper, we analyze the basic principle that magnetic induction was introduced as the control variable, and study the process which micro-displacement signal was got from magnetic induction. And precision driving power based on magnetic induction control is designed. Experiment shows that the dynamic responses of driving power are excellent. |
