摘　　要：分析了冷轧带钢轧机偏心补偿控制的机理,建立了通过傅立叶分析提取偏心信号基波分量作为控制量的偏心补偿动态结构图。针对实际生产中偏心信号给定时存在的问题,分析了偏心信号与位置闭环频率特性的关系,并给出了工程实用的补偿信号给定方法。The effect principle which roller eccentricity affect strip gauge was analyzed, and eccentricity corn pensation control dynamic structural map which apply Fast Fourier Transport （FFT） method was established, To the problems in practice, the relation was analyzed between the eccentricity signal and frequency feature of position closed loop system, and a practical method of giving of compensation signal was put forward.
