In this paper, a novel hierarchy control method is proposed to control hydraulic press machine. The complex hydraulic press machine system is firstly decomposed into two simple sub-systems. Then, the corresponding sub-controller is developed to control every sub-system, which is also able to handle the coupling between sub-systems. Finally, the example study will demonstrate the effectiveness of the...
In view of high-precision requirements for synchronism measurement of huge die forging press, using grating detection technology, the sensors' installation devices of active connection is designed to minimize the incline of moving beam on the impact of measurement accuracy. The analysis models of beam position detection devices are established by Adams, and comparative analysis of two types of detection...
