Simulation of Electro-hydraulic Servo Control System for Steel-strap Running Deviation of Reel

In order to solve the question of steel-strap running deviation in the cold rolling mill production, the paper introduces the principle of auto rectifying deviation in an electro-hydraulic servo control system and de- tailed illustrates the process of establishing mathematical modal of the system and simulation with MATLAB- SIMULINK. While the stability,the accuracy and the speed of response of the system is analyzed. The result indi- cates that the system meet the request both of stability and accuracy of the steel-strap running deviation control system. Its application in cold rolling mill proves the feasibility of the system and high accuracy. It greatly im- proves the productivity.
