Abstract
A control apparatus for a vibration actuator configured to relatively move a contact body in contact with a vibrator with respect to the vibrator using vibration occurring on the vibrator includes a control amount output unit including a trained model trained to, if an instruction about a first speed to relatively move the contact body with respect to the vibrator at is issued, output a first control amount to relatively move the contact body with respect to the vibrator.
Claims37
A control apparatus for a vibration actuator configured to relatively move a contact body in contact with a vibrator with respect to the vibrator using vibration occurring on the vibrator, the control apparatus comprising
- a control amount output unit including a trained model trained to, if a target speed to relatively move the contact body with respect to the vibrator at is input, output a control amount to relatively move the contact body with respect to the vibrator.
A method for outputting a control amount for a vibration actuator configured to relatively move a contact body in contact with a vibrator with respect to the vibrator using vibration occurring on the vibrator, the method comprising
- performing machine learning using training data with a second speed as input and a first control amount as output, the second speed being detected in a case where the contact body is relatively moved with respect to the vibrator by the first control amount, the first control amount being intended to relatively move the contact body with respect to the vibrator in a case where an instruction about a first speed to relatively move the contact body with respect to the vibrator at is issued.
