Inverse Model for the Control of Induction Heat Treatments

Abstract: In this work, we present and test an approach based on an inverse model applicable to the control of induction heat treatments. The inverse model is comprised of a simplified analytical forward model trained with experiments to predict and control the temperature of a location in a cylindrical sample starting from any initial temperature. We solve the coupled nonlinear electromagnetic-thermal problem, which contains a temperature dependent parameter α to correct the electromagnetic field on the surface of a cy… Show more

“…Our numerical model also allows the operator to enter merely the power level into the control system. So, models that are learned with controlled factors are more useful and can be used in reverse for optimization or smart induction heating [19,20]. Furthermore, because exact material data are sometimes unavailable, it is desirable to train a model without explicitly depending on them.…”

“…Compared with other techniques, the strengthening factor of the inductive quenching approach is obviously larger (usually no less than 1.5) than those of the other surface treatment methods. Thus correct design of the manufacturing process parameters becomes necessary to provide the theoretical guidance for the detailed course of working [3] .…”

“…In the context of an inverse problem, fewer studies have been conducted for IH. They are related to the estimation of the power levels using the temperature as input in steel cylinders [47] and the heat transfer coefficient using the surface temperature in a steel billet [48]. In industry, solving the inverse problem for IH can have a number of benefits.…”
