Abstract
A controller and method for efficient tracking and optimizing of a machine set-point, to correct for changes in machine characteristics, can include: (a) defining allowed ranges for output product properties and possible machine set-points, and optimal set-point criteria; (b) finding updated constants for the machine model by calibrating the model; (c) using the updated constants to find all set-points providing a product with properties within the allowed ranges; (d) determining an optimized set-point; (e) operating the machine at the optimized set-point, and obtaining a new output product; (f) comparing the properties of the new output product to the allowed ranges; (g) successfully finishing the procedure as finding a new set point if the properties of the output product are within allowed ranges; and, (h) if the properties of the output product are out of said allowed ranges, repeating the procedure from b.
