Intelligent process control devices and intelligent process control method

摘要

PURPOSE: To provide guidance to an operator by presenting only one guidance value by integrating the plural models of different characteristics in a plant operation so as to have a mutually substitutive and complementary relation. CONSTITUTION: This device is provided with a theoretical expression model 30 for judging the guidance value of the plant operation according to a theory based on the operating conditions of a plant, neuromodel 31 for judging the guidance value according to learning based on the history of running operations, fuzzy control model 32 for estimating the guidance value and the degree of certainty according to inference based on the running conditions and the tendency of movement, integral module 34 for averaging and integrating two kinds of judged results of the theoretical expression model 30 and the neuromodel 31, and integral module 35 for correcting and integrating this integrated result, based on the judged result of the fuzzy control model 32.
