CONTROL DEVICE, CONTROL SYSTEM, CONTROL METHOD, AND PROGRAM

WIPO Patent Application WO/2021/214839

A1

A control object control unit (320) uses preset control parameter values to perform control by outputting to a control object (200) a manipulated variable (MV) signal by which a deviation (E) is eliminated. A frequency component extraction unit (330) extracts a first frequency component signal and a second frequency component signal from the manipulated variable (MV) signal and a control variable (PV) signal. A frequency characteristics calculation unit (350) calculates first frequency characteristics and second frequency characteristics of the control object (200) including phase lag and gain based on the extracted first frequency component signal and second frequency component signal. A model calculation unit (360) calculates a model of the control object (200) based on the calculated first frequency characteristics and second frequency characteristics of the control object (200). A control parameter change unit (380) calculates the value of the control parameters based on the calculated model of the control object (200) and changes the settings.
