Abstract :
The moving beam of large-scale water press´s position holding precisely plays a great important role in works piece quality. Firstly a precisely synchronism control system is studied, then the factors which result in the decline of the synchronism control precision are analyzed, finally a new control strategy based on structure invariance is afforded.
