Modeling and Simulation of Electric-hydraulic Control System for Bending Roll System

Hydraulic bending roll system has become one of key equipments to control the exit strip shape in strip rolling mills. The hydraulic bending roll system of a hot rolling mill was researched and analyzed, and its mathematics models were founded in whole based on the action principle of some representative hydraulic components. At last, the hydraulic bending roll system was simulated with MATLAB by computer. It is obvious that the simulation curves are similar to the real response curves very much.
