Online Dynamic Modelling for Digital Twin Enabled Sintering Systems: An Iterative Update Data-Driven Method

Table 1

List of variables used for the data-driven model.

Notions	Variables	Positions of measure points	Roles	Sampling interval
	The height of mixed materials	Evenly distributed at the head of the sintering bed	Input	1 min
	The air volume of the below	Distributed at the head of the sintering bed
	The air pressure of the below	Distributed at the head of the sintering bed
	The weight of raw material	Located at each raw material storage (including ore, coke, flux, etc.)
	The thickness of red layer	Images from the tail of the sintering bed	Intermediate output
	TS value	Located at sintered ore storage away from the sintering bed	Output	8 hr
