The paper puts forward the idea of fuzzy self - adaptive PID controller design aimed at the time - changing and non - linear electro - hydraulic servo and the simulation analysis combined with Simulink and fuzzy toolbox. The simulation possesses the characteristic of simple construction,direct interface and easy modification etc and obtains the way for fuzzy control rule selection according to the need of PID parameter changing. It also provides the way for software and hardware realization. The system possesses the merit of convenient operation and good interface. It obtains the best parameter through simulation combined with experience and from the simulation result we can see the practicality and validity of this control method and solve the key technology of hydraulic control.
