Abstract
An engine includes an exhaust gas recirculation circuit, an air throttle system, and a charging system. A method to control the engine includes determining a feed forward control command for a first selected one of the exhaust gas recirculation system, the air throttle system, and the charging system based on an inverse flow model of the first selected system. This includes monitoring a first input based upon an effective flow area of the first selected system, monitoring a second input based upon a pressure value within the first selected system, and determining the feed forward control command for the first selected system based upon the first input and the second input. The first selected system is controlled based upon the feed forward control command for the first selected system.
