Control apparatus, control method, and storage medium

A control apparatus comprising:

• an acquisition unit configured to acquire a measurement value measured regarding control target equipment;
• a first control unit configured to output an operation amount of the control target equipment according to the measurement value by at least one of feedback control or feed-forward control;
• a second control unit configured to output an operation amount of the control target equipment according to the measurement value using a model learnt by using learning data;
• and
• a switching unit configured to perform switching between the first control unit and the second control unit by which the control target equipment is controlled, wherein
• the switching unit is configured to perform the switching from a control by the second control unit to a control by the first control unit in response to a fact that a difference between the measurement value and a target value becomes smaller than a reference value.

A control method comprising:

• acquiring a measurement value measured regarding control target equipment;
• outputting an operation amount of the control target equipment according to the measurement value by at least one of feedback control or feed-forward control in a first control phase;
• outputting an operation amount of the control target equipment according to the measurement value using a model learnt by using learning data in a second control phase;
• and
• performing switching between the first control phase and the second control phase by which the control target equipment is controlled, wherein
• the performing switching includes performing the switching from a control in the first control phase to a control in the second control phase according to a difference between the measurement value and a target value.

A non-transitory computer-readable storage medium storing a control program for causing a computer to function as:

• an acquisition unit configured to acquire a measurement value measured regarding control target equipment;
• a first control unit configured to output an operation amount of the control target equipment according to the measurement value by at least one of feedback control or feed-forward control;
• a second control unit configured to output an operation amount of the control target equipment according to the measurement value using a model learnt by using learning data;
• and
• a switching unit configured to perform switching between the first control unit and the second control unit by which the control target equipment is controlled, wherein
• the switching unit is configured to perform the switching from a control by the first control unit to a control by the second control unit according to a difference between the measurement value and a target value.
