Plate thickness, primary plate shape and secondary plate shape comprehensive control method based on influence matrix

The invention provides a strip shape and thickness comprehensive control method. According to the method, the influence of screw-down adjustment, inclined roller adjustment and bent roller adjustment on the plate thickness, the primary plate shape and the secondary plate shape is comprehensively considered. The rolling reduction, the roll tilting amount and the roll bending amount are changed respectively, the plate thickness, the primary plate shape and the secondary plate shape change amount corresponding to the rolling reduction, the roll tilting amount and the roll bending amount are calculated, influence coefficients of rolling reduction adjustment, roll tilting adjustment and roll bending adjustment on the plate thickness, the primary plate shape and the secondary plate shape can be obtained, an influence matrix is formed, then the influence matrix is inversed, a control matrix is obtained, and the control matrix is used for controlling the plate thickness, the primary plate shape and the secondary plat
