1. A method for operating an internal combustion engine in a homogeneous-charge compression-ignition combustion mode, the method comprising:

  • determining an integrated thermal state parameter comprising an aggregation of engine environment factors;

    executing a feed-forward engine control scheme to determine states for engine control parameters, the states for the engine control parameters corresponding to a preferred combustion phasing responsive to an operator torque request and the single integrated thermal state parameter; and

    controlling operation of the internal combustion engine to achieve the preferred combustion phasing using the states for the engine control parameters.
