This paper presented mathematical modeling and simulation of an electro hydraulic servo system by means of a nonlinear analysis method. A nonlinear theoretical state space model was introduced to describe the dynamic performance of the servo system. The actual test responses of the analyzed system were compared with the simulation ones from its simulation model. The results verify the accuracy and validation of the theoretical model and nonlinear analysis method. On the basis of theoretical modeling and simulation, a self tuning PID controller was designed and tested for the servo system, and its control performance was researched by means of simulation.
