PROBLEM TO BE SOLVED: To provide a plate thickness control method of a rolling machine capable of executing proper rolling, while preventing this rolling from becoming excessive control, regardless of a gain adjustment, when feedforward AGC and BISRA-AGC are simultaneously applied.SOLUTION: The plate thickness control method of the rolling machine on the present invention is provided for applying a command value of a draft position calculated by a feedforward AGC 11 and a command value of a draft position calculated by a BISRA-AGC 12, to the rolling machine by determining the command value of the draft position of the rolling machine by the BISRA-AGC 12 on the basis of a determined rolling load deviation, by determining the rolling load deviation of subtracting a rolling load corresponding to the command value of the draft position calculated by the feedforward AGC 11 from an actual value of the rolling load of the rolling machine, when simultaneously using the feedforward AGC 11 for determining the command value of the draft position and the BISRA-AGC 12 for determining the command value of the draft position, on the basis of the actual value of an input side plate thickness of the rolling machine. |
