摘　　要：根据自动控制原理,结合磁致伸缩致动器的结构建立了致动器传递函数模型,在此基础上设计了以TMS320C31为核心的致动器位移闭环控制系统。该控制系统主要由硬件和软件两部分组成。进行了致动器位移控制系统的开环实验和闭环实验,实验结果表明,该系统稳定性可靠、精度高,为致动器在实际精密位移控制中的应用打下了基础。The transfer function model of a magnetostrictive actuator system was established based on the automatic control theory and the system structure. The closed loop displacement control system for the actuator was designed using DSP TMS320C31. The control system is made of two parts, the hardware and the software. The open loop and closed loop experiments were carried out. The experiment result shows that the control system is stable, quick and precise. This result provides a groundwork for the actuator to be used in precision instrument.
