Abstract
A valve timing control apparatus in an internal combustion engine is feedback controlled by a sliding mode control and an abnormality of the sliding mode control is diagnosed. During a slight abnormality other than a crucial abnormality which makes the feedback control impossible, the system is feedback controlled to converge to a target value using only a non-linear term calculated by the sliding mode control.
