Plant controller

Abstract

Abstract PURPOSE:To reduce the burden of an operator by obtaining a parameter in accordance with relations between a present inputted reference value and a monitor value from a plant and using this parameter to correct the reference value when a set value is inputted. CONSTITUTION:A plant of the object to be controlled is controlled by a computer 2; and the set value is read in through a set value input means 6 and is outputted to the plant 1 through a reference value calculating means 10 and a reference value output means 7, and the monitor value is displayed on a CRT display device 3 through monitor value input means 8 and a monitor value display means 9. In this case, a correction reference value calculating means 11, a monitor value average calculating means 12, a corrected parameter calculating means 13, a correction parameter table 14, and a correction reference value 15 are provided. The parameter is calculated in accordance with the reference value and the monitor value from the plant 1 and is always updated. This parameter is used to correct the reference value when the set value is inputted, and the corrected value is outputted to the plant.
