ESTIMATION METHOD FOR A VARIABLE OF A PROCESS OF PROCESS MANUFACTURING USING A REFERENCE VECTOR METHOD

WIPO Patent Application WO2002073323

A3

The invention relates to a method according to which a process variable of a process (1) of process manufacturing is estimated during the progression of the process (1) by means of a reference vector model (2). For preliminarily training said model, a number (N) of pairs of values is defined that comprise one vector of detectable signals (x1, , xn) of the process (1) and one measuring variable (y) each for the process variable to be estimated that corresponds to said measured value. At least one further pair of values that is detected by means of the process (1) is defined for online post-training.
