Integral Control
The integral control analyses the effect of the roll stack eccentricity on measurable mill parameters,such as roll force,and builds up a correction which may be applied to the roll force cylinders in order to compensate for the roll eccentricity present.In this method the signal variations due to eccentricity can be analysed and decomposed into their harmonic components using Fourier analysis.This method decomposes a measured signal’s waveform into a series of sine and cosine components.Once identified these components can be used to construct an eccentricity compensation by identifying those waveforms which are synchronous with the rotation of the Back Up Rolls.To be effective the analysis is taken to the first three harmonics.
The Fourier equation used is:
Where:S0 = Continuous level of measured signal,(ST for total signal,SD for differential signal)
 = Angular displacement of Back Up Roll
i = Number of harmonic
The schematic for the roll eccentricity implementation to be used is given below and gives 3 harmonic resonators for the centreline signal and two harmonics for the differential signal.There are two sets of resonators,one for the top backup roll and a separate set for the bottom backup roll.The top and bottom corrections are summed to give the total eccentricity correction outputs.

分析的整体控制作用的叠加偏心辊轧机的衡量参数,如辊力量,建立了校正可用于轧辊力缸,以弥补目前的轧辊偏心.
在此方法中的信号变化,由于偏心可以进行分析和分解成它们的谐波成分使用傅里叶分析.这种方法分解实测信号的波形为一系列正弦和余弦的组成部分.一旦确定这些组件可以用来建立一个偏心补偿查明这些波形这是同步的轮换后备名册.为了有效的分析是采取前三谐波.
用傅立叶方程是：
地点： S0 =连续水平的测量信号, （圣总信号,差分信号的SD ）
 =角位移后备辊
为I =数谐波
示意图的轧辊偏心执行用于如下并给出3谐波谐振的中心线和两个谐波信号的差分信号.有两套的谐振器,一个用于顶端备份卷和一套单独的底部支撑辊.
顶部和底部更正总结,使总偏心校正产出.
