Abstract
A position detection unit generates a position detection value Pthat 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 P. A controller generates a control instruction value Ssuch that the position detection value Psubjected to the correction matches a position instruction value Pthat indicates the target position of the control target. A driver unit applies a driving signal that corresponds to the control instruction value Sto an actuator. The correction unit corrects the position detection value Psuch that the relation between the position detection value Pand the actual position exhibits linearity that is uniform independent of the temperature.
