Abstract

We discuss the application of the expert system technology to the flatness control problem of the aluminum foil rolling process. Our expert system can adjust the target shape pattern on line for the automatic flatness control system according to the material characteristics and operating conditions. We have modelled the knowledge structure and inference mechanism in the target shape adjustment process that has been done by the experts and developed an expert system. This system has ability to solve the conflict between rules, and keeps consistency in actions. This system infers adaptively considering applied results of the past inference to accomodate the change of the characteristics of the rolling process. Further our model is useful for a class of adjustment problems in the process control.
