Abstract: Methods and apparatuses for calibration and control of various engine subsystems using a target value approach. Under the target value approach, the control of each engine subsystem is separated or decoupled to include a set of target values, or a reference value set. A subsystem has a corresponding target determiner, which provides a target value set, or reference value set, in response to a basis variable set and optionally an overall subsystem target. The basis variable set includes parameters selected to robustly characterize the variables that affect the operation of the particular subsystem. The target determiner is optionally calibrated to provide a reference value set within specifications of the subsystem. A physical subsystem controller operates in response to the reference value set.

Abstract: A system and method are disclosed for calibrating a predictive emission model using steady state data, where the model can robustly predict the emission value in transient conditions. An example emission is smoke. A predictive model for an engine is calibrated in response to a plurality of steady state conditions. During calibration, key basis variables and an emission value are measured and stored into the predictive model. In operation, the online predictive model predicts transient emission events of the emission value in response to online measurements of the key basis variables. The predictive model robustly predicts in-cylinder conditions with an optional virtual sensor instead of an in-cylinder sensor.

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.
