    Abstract: A system for control of an internal combustion system having subsystems, each with different response times. Subsystems may include a fuel system, an air handling system, and an aftertreatment system, each being operated in response to a set of reference values generated by a respective target determiner. Calibration of each subsystem may be performed independently. The fuel system is controlled at a first time constant. The air handling system is controlled on the order of a second time constant slower than the first time constant. The aftertreatment system is controlled on the order of a third time constant slower than the second time constant. A subsystem manager is optionally in operative communication with each target determiner to coordinate control. Generally, dynamic parameters from slower subsystems are treated as static parameters when determining reference values for controlling a faster subsystem.

    Abstract: Methods for adapting system variation for an engine system having an after-treatment system. Measured characteristics of the after-treatment system may be used to predict a model value(s) that is compared to a measured value(s) of the after-treatment system to provide a comparison value. Information relating to high frequency uncertainties in characteristics of the after-treatment system are removed from the comparison value to provide an estimated system variation value. The estimated system variation value may then be used to adapt a system command of a controller. Further, information relating to high frequency uncertainties in characteristics of the after-treatment system may be used by a feed-back controller to determine high frequency adaptation values that may also be used to adjust the system command. The inclusion of the estimated system variation may eliminate reliance on the feed-back controller to provide system adjustments for both high and low frequency uncertainties.

    Abstract: Systems, methods, and apparatus include determining an exhaust gas recirculation (EGR) flow rate. An effective flow area of an EGR system is determined based on a position of an EGR control valve of the EGR system and a pressure differential between an exhaust manifold pressure (EMP) and an intake manifold pressure (IMP) of an internal combustion engine. In response to the effective flow area, the pressure differential between the EMP and the IMP, the EMP, the IMP, and an exhaust manifold temperature the EGR flow rate is determined and a fraction of EGR flow in the charge flow is adjusted in response to the EGR flow rate.

    Abstract: A system for harmonizing knock in a plurality of cylinders included in an engine, the system comprises a plurality of knock sensors, and a controller coupled to each of the plurality of knock sensors. The controller is configured to receive a plurality of cylinder knock values corresponding to each of the plurality of knock sensors, and receive an average knock value. The controller determines a cylinder spark timing offset value for each cylinder in the plurality of cylinders from the average knock value and the cylinder knock values. The controller determines an average spark timing offset value. The controller also determines an adjusted spark timing value for each of the plurality of cylinders by subtracting the average spark timing offset value from a spark timing value of each of the plurality of cylinders.
