PCT No. PCT/SE93/00501 Sec. 371 Date Nov. 29, 1994 Sec. 102(e) Date Nov. 29, 1994 PCT Filed Jun. 7, 1993 PCT Pub. No. WO94/00255 PCT Pub. Date Jan. 6, 1994.The invention relates to an optimization of the control actions "c" via control members for the work rolls during flatness control of strip and comprises a method for evaluation of the control actions and an evaluation device which constitutes an integral part of the control equipment. The control actions are obtained by solution of the relationship c=(ATA)-1xATxf=Bxf, wherein A is a matrix which describes the stress distribution which arises across the strip when the different control members are activated and wherein "f" is a vector which contains the flatness errors obtained after measurement. |
