Abstract

The application of an expert system for an automatic flatness control (AFC) system is discussed. The expert system adjusts the target shape pattern in the AFC system according to the material characteristics and operating condition, and has shown the ability to improve all kinds of aluminum foil throughout a one-year trial in the operational rolling process. Moreover, the algorithm which maintains consistency among multiple control purposes and the adaptive inference method realized in this expert system proved to be useful for a class of adjustment problems in process control
