A controller for an internal combustion engine is disclosed that 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. The controller includes an in-cylinder pressure detector for detecting an in-cylinder pressure in the internal combustion engine. The controller also includes a gravity position calculator for calculating a gravity position of a total heat generation amount during a combustion period based upon the detected in-cylinder pressure. Additionally, the controller includes an opening correcting unit for correcting a position of the intake control valve based upon the calculated gravity position of the total heat generation amount. A process for controlling the intake control valve is also disclosed.
