<p>PURPOSE:To prevent the output of an input signal from being lowered due to increase of its frequency. CONSTITUTION:An automatic plate thickness controller 11 of a rolling mill is provided with a roll gap calculating means 12 which calculates the roll gap of the rolling mill 1 from a plate thickness obtained by measuring the plate thickness of the rolling mill 8, a reciprocal calculating means 13 which detects the frequency of a plate thickness signal, calculates a gain of a rolling-down controller 10 to the frequency and requires the reciprocal of the gain, a multiplying means 14 which multiplies the calculated roll gap by the reciprocal of the calculated gain and an output means 15 which outputs value obtained by multiplication to the rolling-down controller 10.</p> |
