Abstract
A vibration actuator control apparatus includes a control amount output unit. The control amount output unit includes a trained model trained by machine learning configured to output a control amount, if the target speed and a value based on the target position are input to the trained model, to move the contact body relative to the vibrator. The value based on the target position is a value based on a product of first and second values. The first value is a value based on a difference between the target position and a detection position detected from the vibration actuator moved based on the control amount. The second value is a value based on a ratio between the control amount output from the control amount output unit and a value output from the trained model if the target speed and a predetermined value are input to the trained model.
