Abstract

To solve the problem about the stability of the internal dynamics in the feedback linearization control of 80MN titanium alloy forging hydraulic press, according to the characteristics of the structure of the system, a supervision controller is designed with fuzzy control method. By the mixed control with feedback linearization and fuzzy supervision, the tracking accuracy of the output of the system is not only ensured, but also the internal dynamics of the system are ensured to be controlled within a limited range in the tracking process of the output. The result of the system simulation shows the method is very valid.
