Abstract: Control of a turbocharger of a power system is disclosed. A controller may receive a desired value for a parameter of an engine. The controller may receive an operating value of the parameter. The controller may set, based on the desired value and the operating value, a position of an intake throttle valve of the engine to control air flow through a turbocharger of the engine.

Abstract: A controller may identify a plurality of sets of potential parameters associated with operation of an engine, wherein each set of potential parameters includes a potential setting of a turbine of a variable geometry turbocharger (VGT) of the engine and a potential setting of an intake throttle valve (ITV) of the engine. The controller may determine, based on the plurality of sets of potential parameters, a plurality of sets of predicted values, wherein each set of predicted values includes a predicted outlet pressure of a compressor of the VGT and a predicted temperature of an exhaust gas of the engine. The controller may determine respective scores of the plurality of sets of predicted values, and may select, based on the respective scores, a particular set of predicted values of the plurality of sets of predicted values. The controller may thereby control the turbine of the VGT and the ITV.
