    Abstract: A target engine speed module selectively sets M target engine speeds for M future times, respectively, based on one of increasing and decreasing an engine speed. A prediction module, based on a set of possible target values for the M future times and a model of an engine, determines M predicted engine speeds for the M future times, respectively. A cost module determines a cost for the set of possible target values based on comparisons of the M predicted engine speeds for the M future times with the M target engine speeds 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, 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: An engine control system includes a mean effective pressure (MEP) module, an imbalance module, and a phaser control module. The MEP module determines MEPs for combustion cycles of cylinders, respectively, of an engine. The imbalance module selectively determines whether first and second banks of the cylinders are imbalanced based on the MEPs. When the first and second banks of cylinders are imbalanced, the phaser control module selectively adjusts at least one of: a first phaser of an intake camshaft of the second bank of cylinders; and a second phaser of an exhaust camshaft of the second bank of cylinders.

    Abstract: A control system for a turbocharger of a vehicle includes an enable module, an error module, a reduction module, and a boost module. The enable module is configured to: enable reduction in a boost pressure setpoint of a compressor of the turbocharger based on whether a fault exists, load on an engine, and a compressor outlet temperature; and generate an enable signal indicating whether reduction in the boost pressure setpoint is enabled. The error module configured to determine a difference between the compressor outlet temperature and a predetermined limit. The reduction control module is configured to, in response to the enable signal indicating reduction in the boost pressure setpoint is enabled, reduce the boost pressure setpoint based on the difference. The boost module is configured to adjust boost pressure output of the compressor based on the boost pressure setpoint.
