An internal combustion engine operates in a homogeneous-charge compression-ignition combustion mode. A method for controlling the internal combustion engine in response to a fast transient event from a low-load state to a high-load state includes operating the engine with a negative valve overlap between an intake valve and an exhaust valve, and determining a preferred combustion phasing responsive to the high-load state. A preferred EGR mass and a preferred intake valve timing corresponding to the preferred combustion phasing are determined A first intake valve timing is determined in response to a difference between the preferred EGR mass and an actual EGR mass. The intake valve timing is controlled in response to a difference between the preferred intake valve timing and the first intake valve timing.
