| Abstract: | An experiment system of digital closed loop hydraulic synchronization based on stepping motors, digital servo valves and C8051F120 MCU has been designed. In this system, stepping motors are used as the power source of the Numerical control, digital servo valves as the operator of the control system and gratings as the position detecting equipments of hydraulic cylinders. By making full use of the powerful function of C8051F120 MCU, it synchronously controls hydraulic cylinders effectively. The result of synchronous experiments are showed numerically on LCD screen. The hydraulic technology, MCU technology and numeical control technology of students are trained in the system. It could improve students＇ comprehensive quality and produce good effects. |
