Claim One:
1. A plant control apparatus having operation signal generating unit for calculating an operation signal to be supplied to a plant by using a measurement signal representative of a running state amount of the plant, comprising: a measurement signal database for storing a past measurement signal; an operation signal database for storing a past operation signal; numerical value analysis executing unit for analyzing running characteristics of the plant; a numerical value analysis result database for storing numerical analysis results obtained by operating said numerical analysis executing unit; a model for estimating a value of a measurement signal obtained when an operation signal is applied to the plant, by using information in said numerical value analysis result database; learning unit for learning a plant operation method by using said model; a learning information database for storing learning information obtained by said learning unit; a control logic database for storing information to be used by said operation signal generating unit when an operation signal is derived; a knowledge database for storing knowledge regarding the running characteristics of the plant; analyzing unit for processing information in said numerical value analysis result database, by using information in said knowledge database, said learning information database, said operation signal database and said measurement signal database; and an analysis result database for storing an analysis result by said analyzing unit, wherein said analyzing unit includes at least one of learning base analyzing unit for evaluating adequacy of the operation method learnt by said learning unit, signal analyzing unit for evaluating an effect obtained if the operation signal is applied to the plant and presence/absence of an abnormal measurement signal, and knowledge database updating unit for adding information to or correcting information in, said knowledge database.
