The dynamic properties of valve-controlled hydraulic cylinder system are analyzed. The transfer function on load flow and pressure is established. We also establish the simulation model of piston velocity based on PID, using MATLAB. The accuracy of the velocity is proved by simulation results. This research can realize high accuracy of the velocity control by PID controller. It has a certain practical meaning.
