Abstract
A nonlinear observer is developed for metal analysis in the top blown converter process. It is shown that the observer is asymptotically stable and a region of attraction, where the estimation error converges, is derived. Using real plant data from the converter at SSAB Oxelosund AB, the observer is shown to provide accurate estimates of the carbon content
