Fuzzy compensation control based on the synchronization error of 80MN titanium-alloy forging hydraulic press

Aimed at the conflict between the synchronization error and the distribution of the force on the slide in the four-corner leveling control, according to the characteristics of the structure of 80MN titanium-alloy forging hydraulic press, a compensation controller is designed with fuzzy control method based on the feedback linearization decoupling control. Nonlinear flow distribution of all hydraulic cylinders is adjusted to improve the synchronization accuracy of the system further. The result of the system simulation shows the method is very valid.
