The numerical model and Simulink model were established by taking the hydraulic closed-loop position control system for a test platform as a studying object. The system trait in frequency domain was analyzed,and rectified by the proportion integration and differential (PID)controller to improve the system performance. The variety law of system dynamic performance under different pa-rameters was analyzed. Thereby a theoretical basis for the optimal design of the system is provided,and error analysis is made for the rectified system with external load disturbance.
