主　　题：synchronous system hydraulic control optimization 

摘      要：The hydraulic control mode of the synchronous system in Chinese-built 300 MN dieforming hydraulic press was analysed *** improve the deficiency of the existing system,a series investigations were put forward,such as the controlling of inclination angular-velocity,the pre-estimating of compensation,the synchronous cylinder s pressure signal protection,ratio pressure control and changing flow control etc,to increase the system s control accuracy and reliability greatly.
