    摘要： A control system for an engine includes a feedback determination module, a feed-forward determination module, and a valve control module. The feedback determination module generates an exhaust gas recirculation (EGR) feedback value based on engine speed and a difference between desired and measured combustion phasing. The feed-forward determination module generates an EGR feed-forward value based on a difference between desired and measured mass air flow (MAF) rates. The valve control module controls an EGR valve based on the EGR feedback and feed-forward values, an intake manifold absolute pressure (MAP), an engine speed, and an exhaust back pressure (EBP).

    摘要： A control system for a homogeneous charge compression ignition (HCCI) engine includes a timing adjustment module and a combustion control module. The timing adjustment module, per combustion event, advances timings of N fuel injections and retards timings of M fuel injections and spark during a transition from HCCI combustion to mixed-mode combustion. The combustion control module subsequently retards the timings of the N fuel injections and advances the timings of the M fuel injections and the spark to desired timings, respectively, wherein the N fuel injections and the M fuel injections occur sequentially during each combustion event of the HCCI engine, and wherein N and M are integers greater than or equal to zero.
