Abstract :
Based on the uncertainty and disturbance in electro-hydraulic servo system of load, the mathematical model of electro hydraulic servo is set up, the control method of feed forward combining with fuzzy-integrate control is designed, and the control principle of fuzzy-integrate controller is analyzed, the basic structure of fuzzy-integrate controller is designed, the simulation is done on the environment of MATLAB /SIMULINK in order to verify this method. The simulated results indicate that the fuzzy integrate control can improve the control precision of control system. The fuzzy-integrate control combining the feed forward control not only can improve the control precision, but also improve the stability of system about the control of electro-hydraulic servo system.
