Aiming at the problems of single function and difficulty in secondary development of existing pumpcontrolled motor experimental system, a pumpcontrolled motor electrohydraulic proportional speed regulation experimental system was developed based on virtual instrument. The pumpcontrolled motor electrohydraulic proportional speed regulating hydraulic system was designed, the system parameters were matched, the measurement and control system was designed based on virtual instrument, and finally the experimental system was developed. The experimental system has comprehensive functions, friendly interface and is easy to be redeveloped. Openloop and closedloop speed regulation experiments of pumpcontrolled motors can be carried out by it.It effectively promotes the application of electrohydraulic proportional control technology and personnel training.
