Class ModelPredictiveController.QualityConstraint

java.lang.Object
neqsim.process.controllerdevice.ModelPredictiveController.QualityConstraint
Enclosing class:
ModelPredictiveController
public static final class ModelPredictiveController.QualityConstraint extends Object
Representation of a quality constraint handled by the MPC. Each constraint links a measurement device with linear sensitivities describing how the quality responds to control actions, feed composition shifts and feed rate changes. Inequality limits are enforced softly by the quadratic program to keep the process within specification while still penalising unnecessary control effort.
