In this paper, through analyzing the dynamic performance of the electro hydraulic servo system of the position control and the advantages and disadvantages of the conventional fuzzy controller, a PI+ self tuning fuzzy rules controller for a nonlinear servo system was presented. In the proposed control system, the PI controller plays the role of a compensator for the electro hydraulic servo system and the fuzzy controller has the function of self tuning fuzzy rules. Simulation results showed that the PI+ self tuning fuzzy rules controller for the electro hydraulic servo system was quite effective, it could improve control precision and response speed.
