<P>PROBLEM TO BE SOLVED: To allow favorable control to be performed so that a main steam pressure measured value does not greatly vary even when process characteristics of a boiler side as a controlling object change. <P>SOLUTION: When a process characteristic measurement instruction is received, a correction value needed to correct a process model on the boiler side is computed on the basis of an actual main steam pressure measured value "PsPV" output from a manometer fitted to the boiler, a fuel flow rate "Ff" output from a fuel flowmeter, a main steam flow rate "Fs" output from a steam flowmeter fitted to the boiler, a first output value, a second output value, and a third output value output from respective measuring instruments provided to the boiler, etc., thereby correcting the process model of a main steam pressure control predictive computing unit 2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
