Abstract (en)
A sintering process state estimation method includes a process variable calculation step (S1) of calculating an observable process variable using a physical model that takes into account chemical reactions and heat transfer phenomena in a sintering process, a deviation calculation step (S2) of calculating a deviation between an estimated value and an actual value of the calculated process variable, a model parameter adjustment step (S3) of modifying an unknown parameter of the physical model so that the calculated deviation is reduced, and a feature data calculation step (S4) of calculating feature data of the sintering process based on the modified physical model.
