7: Behavior of the model response different trained models while
flooding occurs in the spinning band distillation column.
After the gradient boost algorithm is selected as the most suitable one,
the response of the model will be discussed in detail. The data that the
model receives as input is generated specifically for evaluation and has
not been exposed to the model at any previous time. The following
figures show the response of the model to changes in the speed of the
spinning band. At the beginning a steady state is shown, which is
expressed by a filtered pressure value of about 190 Pa. The spinning
band speed is set to a constant value of 300 rpm. This results in an
almost stable prediction of the pressure difference. The classification
on the top of the diagram shows that the column is working in a normal
operating window (see Figure 8, left hand side).
