超磁致伸缩电液伺服阀驱动机构控制系统设计

摘要

为了实现超磁致伸缩电液伺服阀的快速、准确控制，论述了基于PWM控制的超磁致伸缩电液伺服阀的基本结构和工作原理，设计了基于PicoScope2203数字示波器和STC89C51单片机的超磁致伸缩材料电液伺服阀驱动机构的控制系统。结果表明：该控制系统具有控制精度高、控制迅速、集成度高、操作便捷等特点。%In order to achieve the speedy and precision control of electro⁃hydraulic servo valve based on giant magnetostrictive material, the basic structure and working principle of a kind of Electro⁃hydraulic Servo Valve based on giant magnetostrictive material with PWM control was discussed. A control system for the giant magnetostrictive electro⁃hydraulic servo valve driven machine based on PicoScope2203 Digital Oscilloscope and STC89C51 series MCU was designed. The results show that the control system has properties of high speed and precision, highly integrated and convenient for operation, and etc.
