| Abstract: | Giant magnetostrictive materials (GMM) is a new type of functional materials which is developed in recent years.In this paper,the driving principles of GMM was analyzed and two kinds of driving structure of GMM were given.Then,two control methods were contrastively analyzed and experimentalized,whose control variables were current and flux density respectively. A conclusion can be obtained:the linearity and control precision of microdisplacement actuator based on GMM will be improved and the hysteresis will decrease if adopting the control method based on flux density. |
