WIPO Patent Application WO/2023/286653

Kind Code:

A1

Abstract:

This state estimation method for a sintering process includes: a process variable calculation step (S1) for using a physical model that takes into consideration of a chemical reaction and a heat transfer phenomenon in a sintering process to calculate an observable process variable; a degree-of-deviation calculation step (S2) for calculating a degree of deviation between an actual value and an estimated value of the calculated process variable; a model parameter adjustment step (S3) for correcting an unknown parameter of the physical model so as to reduce the calculated degree of deviation; and a characteristic data calculation step (S4) for calculating characteristic data on the sintering process.
