Abstract
An exemplary method of controlling a gasoline engine operating unthrottled with homogeneous charge compression ignition (HCCI) combustion includes operating the engine with predetermined values of external EGR and internal EGR settings, and burned gas fraction set points for intake and exhaust gases. Repeated adjustments are made to the external EGR and internal EGR settings to move the exhaust and intake gases burned gas fractions toward their state set points. Effects of disturbances in actual operating conditions are thereby minimized.
