超磁致伸缩执行器的驱动电路及接口设计

Design of Driving Circuit and Interface for Giant Magnetostrictive Actuator

介绍了采用超磁致伸缩执行器自行开发的切削振动控制系统,论述了该系统中的超磁致伸缩执行器的驱动电路和接口的设计过程。根据超磁致伸缩材料的驱动特性,该驱动电路设计成一个连续可调的恒流源。

A driving circuit for driving the GMM actuator is proposed.Based on the driving characteristic of the GMM,the driving circuit is designed as a constant current source which can be regulated continuously.
