Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a required acceleration feeling by the suitable control amount according to the operation state of an internal combustion engine. SOLUTION: The feedback correction duty DVFB to be feedback-collected on the basis of the relative rotation angle AC and the target relative rotation angle TAC is calculated (a step S104). The smoothed target relative rotation angle TACSM obtained by smoothing the target relative rotation angle TAC is subtracted from the target relative rotation angle TAC, the target relative rotation angle deviation DELTAC is calculated (a step S106), and the transient correction duty DVTC is calculated (a step S107). The feedback correction duty DVFB in the transient time is suitably corrected (a step S108) by using the transient correction duty DVTC calculated according to the target relative rotation angle TAC. Therefore, control responsiveness of a valve timing control mechanism 50 is improved, and control stability in the steady time can be secured.
