A system and method for controlling an exhaust gas recirculation valve during transient cycles of engine operation to improve fuel consumption efficiency. The system and method includes first determining a flow rate of total mass out of the intake manifold of the combustion engine and the current mass fraction of exhaust gas in the intake manifold of the combustion engine, calculating a mass flow rate for exhaust gas into the intake manifold that is based on the flow rate of total mass out of the intake manifold and the current mass fraction of exhaust gas in the intake manifold, and actuating a control valve to a position based on the calculated mass flow rate for exhaust gas into the intake manifold.
