Title:
PLANT CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/112074
Kind Code:
A1
Abstract:
According to this plant control device, on the basis of a correction target- value candidate of control output, a reference governor uses a prediction model in which a closed loop system including a plant and a feedback controller are modeled to sequentially calculate across a limited prediction horizon a prediction value for a plant state quantity that includes a specific state quantity to which conditions are assigned. When doing so, if the prediction value of a specific state quantity conflicts with the conditions in relation to a correction target-value candidate, the reference governor excludes such correction target-value candidate from a final correction target value. As a result of the foregoing, the sufficiency of the conditions is guaranteed and the calculation load necessary for correction of the target values of control output is reduced.
