System Description
Another control problem (besides the continuous caster) arising in the steel industry is the control of the exit steel thickness in a rolling mill. The diagram below shows the layout of a rolling mill, with thick steel going in one side, and thin steel coming out the other.
Overview of the Example
It is recommended that you follow the example in order, but you may skip ahead if you wish:
| Part 1 | Basic roll model, including time delay |
| Part 2 | Smith controller to remove the effect of the time delay |
| Part 3 | BISRA gauge (soft sensor) |
| Part 4 | Cause of sinusoidal disturbance |
| Solution of eccentricity problem |
