Multi variable flatness control system |
摘要 |
Method of measuring and/or controlling flatness during rolling. The flatness deviation is measured and expressed using orthogonal polynomials. A controlled variable is generated using an Internal Mode Control by comparing the expressed deviation with values of orthogonal polynomials supplied by a model. The comparison provides a control difference to control variables that influence bending, pivoting and axial displacement of the rolls and by multizone cooling.
