Patent ID: 8391998

Claim:
A computer-implemented method for controlling and/or regulating an industrial process ( 10 ) for manufacturing or processing products ( 100 ), the method comprising: forming, by a computer, a physicomathematical model ( 15 ) of the industrial process ( 10 ) to calculate controlled variables to control or regulate the industrial process; acquiring, by the computer, a number (M) of measured values (TF−TH) during the manufacture or processing of the product ( 100 ); and correcting, by the computer, the model ( 15 ) with the aid of a number (M) of primary correction factors (k 1 ), the number (M) of primary correction factors (k 1 ) being equal to the number (M) of measured values (TF−TH), wherein the model ( 15 ) is corrected with the aid of a number (N−M) of secondary correction factors (k 2 ), and a number (N) of all the correction factors (k 1 , k 2 ) being greater than the number (M) of all the measured values (TF−TH), at least the secondary correction factors (k 2 ) being calculated numerically, wherein the correction factors (k 1 , k 2 ) are determined from the model ( 15 ) and the number (M) of the measured values (TF−TH) with the aid of an iterative optimization algorithm in the case of which a multiplicity of test values are specified for each of the correction factors (k 1 ,k 2 ), and wherein the optimization algorithm follows a gradient descent method of optimization.
