<P>PROBLEM TO BE SOLVED: To perform proper control by determining optimum weight matrices Q, R by which interference between both control is suppressible in plate thickness/tension control of a tandem rolling mill using an integration type optimum servo system. <P>SOLUTION: In the method for controlling the tandem rolling mill 1, by which the control of a sheet thickness control system for controlling sheet thickness and a tension control system for controlling interstand tension is performed when performing the rolling of a rolling stock 3 with the tandem rolling mill 1 provided with a rolling stand 2a on the upstream side and a rolling stand 2b on the downstream side which are continued, by setting a state equation of the tandem rolling mill 1, setting a first assessment function having the weight matrices Q, R to perform the design of an integration type optimum servo system to the state equation and setting a second performance function for determining the weight matrices Q, R such that the interference between the sheet thickness control system and a tension control system is minimum, the sheet thickness control system and the tension control system are controlled by using the weight matrices Q, R determined by the second performance function. <P>COPYRIGHT: (C)2012,JPO&INPIT |
