ABSTRACT:
A positioning control apparatus includes a position detector102which detects the position of a positioning object101, a target position generator103which generates a target position signal based on an output from the position detector, and a driving unit104which drives the positioning object based on an output from the target position generator. The target position generator103includes a control unit which sets a temporary target position of the positioning object and performs the learning of a reference position of the positioning object. A control gain given to the driving unit includes a first control gain, which is valid until the positioning object reaches the set temporary target position, and a second control gain, which is smaller than the first control gain and which is valid after the time when the positioning object has reached the temporary target position until the reference position learning is completed.
