1. A controller for an internal combustion engine which includes an intake control valve adjusting a flow of intake air in the internal combustion engine and controls a position of the intake control valve in accordance with an engine operating condition comprising:
an in-cylinder pressure detector for detecting an in-cylinder pressure in the internal combustion engine;
a gravity position calculator for calculating a gravity position of a total heat generation amount during a combustion period based upon the in-cylinder pressure detected by the in-cylinder pressure detector; and
an opening correcting unit for correcting a position of the intake control valve based upon the gravity position of the total heat generation amount calculated by the gravity position calculator.
