Controller, control method, and computer-readable recording medium for controlling controlled object with trained model

A non-transitory computer-readable recording medium having stored therein a control program configured to cause a computer to execute:

• acquiring process data for an actually used controlled object;
• converting the acquired process data based on at least one of a target set value and parameters for the actually used controlled object;
• and
• calculating a manipulated variable for the actually used controlled object by use of the converted process data and a trained model, wherein
• outputting a manipulated variable for the actually used controlled object by inputting the converted process data into a trained model, wherein
• upon receiving input of process data for a specific controlled object, the trained model outputs a manipulated variable for approximating process data for the specific controlled object to a specific target set value, the trained model being trained using a target set value that may be the same or different from the specific target set value, and
• the parameters include parameters for specifying a relation between manipulated variables for the actually used controlled object and process data obtained by use of the manipulated variables, wherein
• the control program is further configured to execute:
• adjusting a mapping function and an inverse mapping function based on a ratio between at least one of the target set value and the parameters for the actually used controlled object and at least one of the specific target set value for the specific controlled object and the parameters for the specific controlled object, the inverse mapping function being an inverse function of the mapping function, and
• switching a control mode between a first control mode under which the manipulated variable calculated by a processor is fed to the actually used controlled object, and a second control mode under which a manipulated variable calculated by a Proportional-Integral-Differential controller is fed to the actually used controlled object, wherein
• the outputting the manipulated variable includes conversion of the acquired process data by use of the adjusted mapping function and inverse conversion of data that is calculated using the converted process data and the trained model, the inverse conversion being performed using the inverse mapping function of the mapping function.
