Patent ID: 7813819

Claim:
A control system for a control subject having a combustion apparatus, comprising: a basic control command operating unit configured to input measurement data of the control subject having a combustion apparatus to operate an operation command value to the control subject; a fuel data storage unit configured to store data sets of operation parameters of the combustion apparatus and components in combustion gas for a plurality of fuel compositions to be supplied to the combustion apparatus; a running results database for storing past running results values of the control subject; a data creating unit configured to calculate distances between data of the past running results values of the control subject and the data sets and determine a data set in which a distance between data is minimum; a modeling unit configured to model a relationship between operation parameters of the combustion apparatus and components in combustion gas of the combustion apparatus by using the data set determined by the data creating unit; and a correcting unit configured to calculate combustion apparatus operation parameters with which components in a better condition than the components in current combustion gas are provided by using a model of the modeling unit and to correct operation command values of the basic control command operating unit with the calculated operation parameters, wherein a data flag is provided in a new data set created by the data creating unit in order to distinguish numeral value analysis data and running results data of the new data set, and wherein the modeling unit is configured to regard running results data as important data when creating a model by distinguishing the data flag.
