1. A method for controlling an internal combustion engine, the engine including an exhaust gas recirculation (EGR) valve driven in response to an EGR valve command signal, the method comprising:
generating a desired EGR valve discharge coefficient based at least in part on a set of engine parameters;
generating the EGR valve command signal using the desired EGR valve discharge coefficient and a Discharge Coefficient to EGR Valve Position model; and
transmitting the EGR valve command signal to the EGR valve.
