In this paper, a FUZZY + PI control strategy for electro- hydraulic servo fatigue testing machine based on micro computer is introduced. The robust nature of fuzzy control gives the control systema good anti-disturbance ability, and the adding of MD control to the system improves the system's static accuracy and the elimination of wave distortion. Good static and dynamic performances are gotten in step response, robust performance and waveform following experiment of this FUZZY+PI control system. Experimental resultsprove that the introduced control strategy is quite successful in electro-hydraulic servo fatigue testing machine, and it can also be used in other electro-hydraulic servo system.
