Abstract
An off-gas treatment system is a vital component of smelter roaster processes as it ensures operation is in accordance with environmental regulations in terms of hazardous emissions. It is, therefore, paramount that a well-designed control structure be incorporated into the system. Analysis of the off-gas treatment processes for a roaster using a systematic control design procedure to provide the necessary verification to current industrial practices for controlling these processes was carried out. We approached this by conducting a top-down (steady-state) analysis based on an available nonlinear model of the process. The results provide insight into, and potential improvement of, the control of the off-gas system. Through designing the bottom-up structure, a feedback control structure was developed to give robust and effective control in terms of disturbance rejection capabilities. The proposed control structure provides for improved performance in an easy form to implement.

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
