CONTROL MODEL IDENTIFICATION METHOD, CONTROL MODEL IDENTIFICATION APPARATUS AND PROGRAM

摘要

To identify, using closed-loop response data during an operation, a control model in a situation in which a target value is constant and a control amount and an operation amount vary due to an unknown disturbance.SOLUTION: A control model identification method is for identifying a control model of a control target when a target value of a control amount of the control target is constant, and causes a computer to execute: a first setting process for setting, using parameters of a PID control that controls the control target, a disturbance response reference model that simulates a control response from a disturbance; an optimizing process for calculating, using the disturbance response reference model and closed-loop response data of the control target controlled by the PID control, an optimized parameter that contains an optimized control parameter for the PID control by FRIT method; and a control model calculating process for calculating the control model using the optimized parameter.SELECTED DRAWING: Figure 7
