Abstract
An electric apparatus for controlling movement of a target object by performing first and second feedback controls, based on a detection signal obtained from detecting the movement of the target object, generates an operation quantity on the target object based on first and second operation quantities for the second feedback control if one of a predetermined target value and an estimated first state quantity of the target object is higher than a first threshold value, and generates the operation quantity on the target object using only the first operation quantity from among the first and the second operation quantities if one of the target value and the first state quantity of the target object is lower than the first threshold value.
