Abstract: A system according to the principles of the present disclosure includes a first model predictive control (MPC) module and an engine actuator module. The first MPC module generates predicted parameters based on a model of an engine and a set of possible target values and generates a cost for the set of possible target values based on the predicted parameters and a desired exhaust enthalpy. The first MPC module also selects the set of possible target values from multiple sets of possible target values based on the cost. The engine actuator module adjusts an actuator of the engine based on at least one of the target values.

Abstract: A method to determine reference actuator positions for a gasoline engine, includes entering a base torque request, a known spark advance, a known CAM position and a known exhaust gas recirculation (EGR) valve position into an inverse torque model to generate a first iteration desired air per cylinder (APC) value. The first iteration desired APC value is passed through a deadband filter to produce a filtered first iteration desired APC signal. A Predicted As Cal (PAC) spark advance is calculated for the filtered first iteration desired APC value. The PAC spark advance and the base torque request are modified, and data from a first lookup table is entered to generate a second iteration desired APC value.

Abstract: A prediction module, based on a set of possible target values for M future times and a model of an engine, determines predicted torques of the engine for the M future times, respectively. M is an integer greater than one. A cost module determines a cost for the set of possible target values based on comparisons of the predicted torques for the M future times with engine torque requests for the M future times, respectively. A selection module, based on the cost, selects the set of possible target values from a group including the set of possible target values and N other sets of possible target values, wherein N is an integer greater than zero, and sets target values based on the selected set of possible target values. An actuator module controls an engine actuator based on a first one of the target values.

Abstract: A control system includes a control module that receives a first request corresponding to a control value for at least one of a plurality of actuators, selectively receives a second request associated with a predicted future control value for at least one of the plurality of actuators, determines a target value for the actuator based on the first request if the second request was not received, and generates a reference signal representing the second request if the second request was received. The reference signal indicates at least one of a predicted increase in the control value and a predicted decrease in the control value. A model predictive control module receives the reference signal and adjusts one of the plurality of actuators associated with the predicted future control value based on the reference signal.
