| Abstract: | The physical characteristics o giant magnetostrictive material are discussed, and the hysteresis phenomenon of accurate control of giant magnetostrictive actuator is also pointed out by experimental ob- servation of the hysteresis. In order to improve the effects of hysteresis, the giant magnetostrictive materi- al is over-magnetised. The effectiveness of this method is theoretically analyzed validated through the ex- periment. |
