Control apparatus of vibration actuator, method for controlling vibration actuator, driving apparatus, imaging apparatus, interchangeable lens, and automatic stage

摘要

A control apparatus of a vibration actuator performs control of the vibration actuator using a control amount calculated using both of a first deviation which is a difference between a command value and a relative position, and a gain changed in accordance with a second deviation which is a difference between a target position and the relative position, so as to reduce the gain in accordance with reduction of the second deviation.
