Abstract
A control device for a WG actuator includes a feedback control unit for performing feedback control on the WG actuator in such a way that the position of a shaft detected by a position sensor gets close to a target position, and an abnormality detecting unit for providing an instruction to move the shaft in an axial direction for the feedback control unit, and for detecting an abnormality in the WG actuator on the basis of a result of a movement of the shaft, the movement being detected by the position sensor while the feedback control unit performs the instruction.
