Abstract

See full text

A position detection unit generates a position detection value PFB that indicates the position of a control target. A temperature detection unit generates a temperature detection value that indicates the temperature. A correction unit corrects the position detection value PFB. A controller generates a control instruction value SREF such that the position detection value PFB_CMP subjected to the correction matches a position instruction value PREF that indicates the target position of the control target. A driver unit applies a driving signal that corresponds to the control instruction value SREF to an actuator. The correction unit corrects the position detection value PFB such that the relation between the position detection value PFB and the actual position exhibits linearity that is uniform independent of the temperature.
