Abstract：

For requirements of the high performance control on forging manipulator cart walking hydraulic servo system and the difficulty in achieving high performance control of the walking system under traditional PID control, the experimental research of fuzzy control the forging manipulator cart walking system was carried out systematically. A new type of fuzzy controller was adopted, and the fuzzy control rule database had a determinate mathematical model. Because the fuzzy controller structure was similar to the conventional PID, the parameters of the fuzzy controller could be adjusted by the conventional PID to avoid the randomness existed in traditional fuzzy design and experiences. The experimental study shows that, compare with the conventional PID controller, the fuzzy controller method has advantages of small overshoot, high control precision, strong robustness and easy engineering implementation, etc., and it provides a feasible method for the forging manipulator cart walking system as well as the similar hydraulic servo system control.
