Research on Shape Signal Smoothing Processing of Cold Rolling Strip

In the process of measuring the shape of the cold rolling strip, by combining proportion compensation with slope compensation, the signal error of edge shape should be compensated reasonably. In addition, corresponding solutions are proposed to solve the channel signal loss or the discontinuous transverse shape value which takes place occasionally in the shape measuring roller. These solutions could improve the stability of shape measuring signal, avoid serious accidents of controlling mill caused by abnormal shape signals and achieve reliable shape control without worries
