The electro-hydraulic generator of spring load is used in experimental studies to upload electro-hydraulic position control system with spring load. Aimed at the problem of the spring load significantly influenced the generator's system stability, a conventional compensation method was used to analyze and solve the problem made on system stability by influence of stiffness load, and the feed forward control was specifically introduced to solve problem that negative stiffness load taken to the system stability. The correction methods are confirmed to be effective by simulation results, which also show that the system's response speed and control precision can meet the request.
