Abstract
Provided is a control apparatus including 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.
Claims11
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 according to a difference between the measurement value and a target value, and
- wherein the switching unit is configured to perform the switching from the control by the first control unit to the control by the second control unit in response to a state occurring multiple times where the difference between the measurement value and the target value is higher than a reference value within a reference time window.
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 is performed according to a difference between the measurement value and a target value, and
- wherein the performing switching is performed by switching from control in accordance to the first control phase to control in accordance to the second control phase in response to a state occurring multiple times where the difference between the measurement value and the target value is higher than a reference value within a reference time window.
A 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 according to a difference between the measurement value and a target value, and
- wherein the switching unit is configured to perform the switching from the control by the first control unit to the control by the second control unit in response to a state occurring multiple times where the difference between the measurement value and the target value is higher than a reference value within a reference time window.
