    Abstract: A torque requesting module generates a torque request for an engine based on driver input. A model predictive control (MPC) module: identifies sets of possible target values based on the torque request, each of the sets of possible target values including target effective throttle area percentage; determines predicted operating parameters for the sets of possible target values, respectively; determines cost values for the sets of possible target values, respectively; selects one of the sets of possible target values based on the cost values; and sets target values based on the possible target values of the selected one of the sets, respectively, the target values including a target pressure ratio across the throttle valve. A target area module determines a target opening area of the throttle valve based on the target effective throttle area percentage ratio. A throttle actuator module controls the throttle valve based on the target opening.

    Abstract: A method of controlling the operation of an air charging system is disclosed. A plurality of output parameters of the air charging system are monitored. An error between each one of the monitored output parameters and a target value thereof is calculated. Each one of the calculated errors is applied to a linear controller that yields a virtual input which is used to calculate a plurality of input parameters for the air charging system. Each one of the input parameters is used to determine the position of a corresponding actuator of the air charging system and operate of the actuators according to the determined position thereof. The inputs parameters are calculated with a non-linear mathematical model of the air charging system configured such that each one of the virtual inputs is in a linear relation with only one of the output parameters.

    Abstract: Disclosed are model predictive control (MPC) systems, methods for using such MPC systems, and motor vehicles with selective catalytic reduction (SCR) employing MPC control. An SCR-regulating MPC control system is disclosed that includes an NOx sensor for detecting nitrogen oxide (NOx) input received by the SCR system, catalyst NOx sensors for detecting NOx output for two SCR catalysts, and catalyst NH3 sensors for detecting ammonia (NH3) slip for each SCR catalyst. The MPC system also includes a control unit programmed to: receive desired can conversion efficiencies for the SCR catalysts; determine desired can NOx outputs for the SCR catalysts; determine maximum NH3 storage capacities for the SCR catalyst; calculate the current can conversion efficiency for each SCR catalyst; calculate an optimized reductant pulse-width and/or volume from the current can conversion efficiencies; and, command an SCR dosing injector to inject a reductant into an SCR conduit based on the calculated pulse-width/volume.

    Abstract: An internal combustion engine includes an air charging system with a boost air system. A method to control the boost air in the air charging system, decoupled from the air and EGR system controls, includes monitoring a reference boost pressure and operating parameters of the air charging system; creating a turbocharger energy balance model of the air charging system; applying feedback linearization control to the turbocharger energy balance model to create an approximately linearized feedback system; and determining a boost control command for the air charging system using the approximately linearized feedback system based on the monitored reference boost pressure and the monitored operating parameters of the air charging system. The boost air in the air charging system is controlled based upon the boost control command.

    Abstract: A system or method for determining virtual data of a system, relative to a measurement point having a sensor located nearby, is determined by a controller. The system calculates modeled data at the measurement point, filters the modeled data to determine filtered data, and calculates a differential between the modeled data and the filtered data to determine a compensation term. The system also determines raw-sensed data from the sensor at the measurement point, and combines that raw-sensed data with the compensation data to calculate the virtual data at the measurement point. In some configurations, the modeled data is determined from a physics-based model. Furthermore, filtering the modeled data may include using a low-pass filter, and a time constant for the low-pass filter may be calculated based on operating conditions of the system.
