Abstract
In this paper, we present the notion of model-based virtual sensors and virtual core temperature observers in a thermoforming process. The concept of model-based virtual sensors allows for additional surface temperature measurement points in addition to the already existing infrared sensors. This leads to improved controllability of the plastic sheet temperature as well as increased accuracy in temperature zoning, thus eliminating the use of extra infrared sensors, which significantly reduces the cost of the control system. The problem of core sheet temperature measurement is also addressed through the application of a closed-loop Luenberger core temperature observer to estimate the center-plane temperature of the plastic sheet since it is not practical to have any kind of actual core temperature measurement during the heating process. The two concepts of virtual sensors and virtual core temperature observers are then combined to form an overall observer based closed-loop control system. Finally, the functionality, performance, and robustness of the new system is investigated through simulation of an industrial-type thermoforming machine.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
