摘要
为了实现超磁致伸缩执行器(GMA)精密的位移控制,需要采取一定温控设施保证超磁致伸缩材料(GMM)工作在特定温度情况下;针对超磁致伸缩材料对温度的敏感性,在GMM智能构件的基础上提出了一种改进的强制水冷温度控制策略;利用单片机控制系统实现了对超磁致伸缩执行器的温度控制,实验结果表明了该控制策略可以保证GMA工作在恒温,验证了策略的有效性;对超磁致伸缩材料微驱动应用具有实际的工程意义。
To realize precision displacement control for giant magnetostrictive actuator, a temperature control approach is necessary for constant giant magnetostrictive material （GMM） temperature. Because of inherent GMM temperature sensitivity, an improved forced water - cooled strategy is proposed. The giant magnetostrictive actuator temperature control system is realized by u- sing single - chip microcomputer control system. The validity of control strategy is proved by experiment. The temperature control strategy for giant magnetostrictive micro - driven actuator is of important significance to the actual engineering.
