Multivariable prediction control system

摘要

PROBLEM TO BE SOLVED: To facilitate evaluating controllability in a multivariable prediction control system using a process model.SOLUTION: The multivariable prediction control system for predicting change of a process value of an actual process with the use of a process model corresponding to the actual process and controlling the actual process, comprises a trend display control unit which, when accepting an instruction at the past time, displays in an overlapping manner a trend of a process prediction value at the past time and a trend of a process actual value at the time following the past time.SELECTED DRAWING: Figure 1
