Abstract
A control system for an internal combustion engine is provided with a crankshaft, an intake camshaft with an intake cam, a timing chain, an intake variable valve timing mechanism configured to be able to change at least one of an opening timing and closing timing of an intake valve by controlling a phase of the intake cam, and an electronic control unit configured to set in advance a periodic correction coefficient to vibrate by a period identical to a rotational period of the timing chain and to control the intake variable valve timing mechanism by the periodic correction coefficient to make the phase of the intake cam a target phase.
