The application of the hydraulic servo technique in fms

摘要

First, the general plan of the angle steel's FMS is briefly described in this paper. Second, in comparison with stepper motor and large inertia direct current servo motor, valve-control hydraulic one is shosen, and the design procedure of its' systgem is discussed in detail. At last, its' advantages such as fine stability, high accuracy and stable productivity efficiency is verified by computer simulation.
