Gauge Compensation and Control for Rolling Mill Based on the LS Method

A method based on the least square （LS） is introduced to analyze and calculate the characteristic parameters of periodic exit gauge error of the roiling mill, and a new solution is proposed to control the rolling mill and realize the compensation for the exit gauge error. The simulation and the field data processing results suggest that this method could compute the periodic fluctuation of the exit gauge error including entrance gauge and rolling eccentricity quickly and accurately, compensate and control exit gauge of the rolling mill.
