应用于自动化设备的超磁致伸缩微位移驱动器的研究

摘要

A drive of giant magnetostrictive material was designed and its structure and working principle. Based on that,mathematical model of GMA was set up for time-domain and frequency domain analysis. Because of the existence of position error,a PID controller which results effective control was designed and showed that GMA designed was reasonable.%设计了一种利用超磁致伸缩材料的驱动器并对其结构和工作原理进行说明,在此基础上建立所研制驱动器的数学模型,进行时域和频域特性分析,由于存在位置误差,设计了PID控制器进行校正,得出控制器的有效控制效果,表明了设计的超磁致伸缩驱动器的合理性.
