A typical field of application of a pilot control is, for example, the optimization or supplementation of a chamber furnace control by a pilot control model. For a chamber furnace, a 1-dimensional transient energy balance model was created, parameters with uncertainties (e.g. surfaces from dimension reduction, material data) were provided with linear factors.
The model was trained with different power/temperature curves from preliminary tests. The graph shows the differences of the temperature curves at the control thermocouple of the furnace control before and after the use of the pilot control with the trained process model. This shows how much a good process model can improve the temperature control in the furnace.
