Abstract
This paper introduces the composition and principle of the electro-hydraulic position servo control system.The traditional PID controller will show bad dynamic and static state capability when a disturbance happens.The design of the Fuzzy-PID controller combining the advantages of PID control and fuzzy control with simulation by the Simulink software shows that the Fuzzy-PID controller has a better dynamic and static state performance than traditional PID controller.
