Abstract
A physical model identification system according to the present invention first uses actual data sampled from a manufacturing line to learn a statistical model expressing a controlled object in the manufacturing line. Next, this system creates numerical quantity data quantifying an input-output relationship between a registered input variable and a response variable of a learned statistical model. Next, this system identifies a correction coefficient of a physical model such that a relationship, expressed by the numerical quantity data, between the registered input variable and the response variable is maintained. An identified correction coefficient is reflected in the physical model implemented in a calculator controlling the manufacturing line. Accordingly, prediction precision of preset values and control values of the controlled object by a practical model is improved, and a stable operation of the manufacturing line and high quality production become possible.
