Abstract: An engine includes an exhaust gas recirculation system with a high pressure exhaust gas recirculation loop and a low pressure exhaust gas recirculation loop, and an air charging system. A method of controlling the air charging system includes monitoring an actual exhaust gas recirculation rate, operating conditions of a compressor and turbine in the air charging system. A compressor flow is determined based on a target exhaust gas recirculation rate, a target intake manifold pressure and the actual exhaust gas recirculation rate. A power requested by the compressor is determined based on the compressor flow, the target intake manifold pressure, and the monitored operating conditions of the compressor. A power to be generated by the turbine is determined based upon the power requested by the compressor. A turbine flow is determined based upon the power to be generated by the turbine and the monitored operating conditions of the turbine. A system control command is determined based on the turbine flow and the monitored operating conditions of the turbine. The air charging system is controlled based on the system control command.

Abstract: An engine assembly includes a control module configured to receive a torque request and an engine configured to produce an output torque in response to the torque request. The control module includes a processor and tangible, non-transitory memory on which is recorded instructions for executing a method for supervisory model predictive control. The control module includes a multi-layered structure with an upper-level (“UL”) optimizer module configured to optimize at least one system-level objective and a lower-level (“LL”) tracking control module configured to maintain at least one tracking parameter. The multi-layered structure is characterized by a decoupled cost function such that the UL optimizer module minimizes an upper-level cost function (CFUL) and the LL tracking control module minimizes a lower-level cost function (CFLL). The system-level objective may include minimizing fuel consumption of the engine and the tracking parameter may include delivering the torque requested to engine.

Abstract: A method is disclosed for controlling a two-stage turbocharger system having low-pressure and high-pressure turbochargers in line, sequentially, with an engine. The turbochargers include a low-pressure (LP) turbine and an LP compressor, and a high-pressure (HP) turbine and an HP compressor. The LP compressor feeds the HP compressor, which feeds the engine intake. The engine exhaust feeds the HP turbine, which feeds the LP turbine. The method determines a total boost pressure, which provides combustion reactant for the engine. The method calculates an LP compressor power from the determined total boost pressure, and an LP turbine flow from the LP compressor power. The low-pressure turbocharger operates at the calculated LP turbine flow. The method calculates an HP compressor power from the determined total boost pressure, and an HP turbine flow from the HP compressor power. The high-pressure turbocharger operates at the calculated HP turbine flow.
