Abstract: With the rapid development of electro-hydraulic proportional control technology applications and pump motor control system, hy-draulic system in order to make the production process to meet the higher demands on system performance, the need to improve the re-sponse characteristics of the hydraulic system and reliability, and the establishment of the system accurate model is the foundation to further improve and perfect the system design. Chang'an University using electro-hydraulic proportional pressure-flow control experiment bench resulting experimental data, combined with Matlab software, using ARMAX model identification method for electro-hydraulic proportional pump controlled motor system conducted experiments to identify, and the system has been applied to the control strategy simulation.
