摘要
An engine control system for a homogeneous charge compression ignition (HCCI) engine includes a position determination module, a position correction module, and a valve control module. The position determination module determines an initial position of an exhaust gas recirculation (EGR) valve based on a predetermined function of a desired EGR flow, intake manifold pressure, exhaust manifold pressure, and exhaust gas temperature. The position correction module determines a position correction for the EGR valve based on pressure in a cylinder of the HCCI engine. The valve control module commands the EGR valve to the initial position during a transition from spark ignition (SI) combustion to HCCI combustion, and commands the EGR valve to a final position within a predetermined period after the transition, wherein the final position includes a sum of the initial position and the position correction.
