Title:
TEMPERATURE CONTROL DEVICE FOR ROLLED MATERIAL
Document Type and Number:
WIPO Patent Application WO/2017/046846
Kind Code:
A1
Abstract:
Provided is a temperature control device (11) for a rolled material (7) whereby the impacts of a model error value can be suppressed in a short period of time. The temperature control device (11) for the rolled material (7) is provided with: a controller (12) for taking a deviation between a target value and feedback value of the temperature of the rolled material (7) as an input to compute a control quantity for a cooling device (5); a first feedback unit (13) for using a temperature model (13a) not including a dead time on the basis of the control quantity to compute a predicted value for the temperature of the rolled material (7) and for feeding back the predicted value; and a second feedback unit (14) for using a dead time model (14a) to compute a value by which phase is delayed by an amount commensurate with the dead time relative to the predicted value of the temperature of the rolled material (7), computing the deviation between a measured value of the temperature of the rolled material (7) and the value obtained by delaying phase by the amount commensurate with the dead time with respect to the predicted value of the temperature of the rolled material (7), and feeding back a value obtained by having this deviation pass through a low-pass filter (14b).
