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.
