Abstract
A strip thickness control apparatus for a rolling mill includes a strip thickness gauge provided on a delivery side of the rolling mill, a moving distance calculating module for calculating a moving distance of the strip from the rolling mill, a rolling roll angle-of-rotation calculating module for calculating an angle of rotation of the rolling roll, a strip thickness deviation calculating module for calculating a deviation of the strip thickness from a target value of the measured value of the strip thickness, a strip thickness deviation storage module for storing the strip thickness deviation by adding it for every angle of rotation of the rolling roll, a strip thickness deviation input determining module for determining an input timing for inputting the strip thickness deviation to the strip, thickness deviation storage, a strip thickness deviation output determining module for determining an output timing for outputting the strip thickness deviation stored in the strip thickness deviation storage module, and a manipulated variable calculating module for fetching the strip thickness deviation at the output timing determined and determining a manipulated variable of a roll gap c…
