Abstract
To overcome the long servo cycle, poor stability, weak parameter adaptability and other poor performances of domestic developed electro-hydraulic servo system of milling, it adopts the embedded design to set up electro-hydraulic servo control system based on STM32 MCU to realize precise control of copper tube surface processing. After an overall design of control system was proposed, the hardware design based on STM32 MCU is expatiated, and a complex control algorithm is designed based on position control and force control. Field tests indicate that the designed electro- hydraulic servo control system is worthy to popularize with its high precision, fast response, stable performance, and the quality and efficiency of copper tube processing have been improved.
