Title:
CONTROL METHOD AND CONTROL DEVICE OF ROLLING MACHINE
Document Type and Number:
Japanese Patent JP2016074025
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To control a roling machine based on an estimation result, by highly accurately estimating a rolling state of a rolled material even when the number of unknown rolling characteristic value is more than the number of equation constituted of a rolling model.SOLUTION: A control method of a rolling machine on the present invention includes a construction step of constructing the optimization problem composed of an evaluation function composed of a rolling model for predicting a rolling phenomenon of a rolled material S in a plurality of roling stands F1-F7 and a constraint expression on a variation in the rolling model, an estimation step of estimating an unknown variation included in the rolling model by solving the optimization problem constructed in the construction step by substituting a measured value in a measurable variation in the rolling model and a control step of controlling the rolling machine by using the unknown variation estimated in the estimation step.SELECTED DRAWING: Figure 1
