Assignee: CATERPILLAR INC.
Field: Engines, pumps, turbines (Mechanical engineering)
Classification: CPC F  Y | IPC F

Claim 0:
1. A method, comprising:
identifying, by a controller, a desired outlet pressure of a compressor of a variable geometry turbocharger (VGT) and a desired temperature of an exhaust gas of an engine;
identifying, by the controller, a plurality of sets of potential parameters associated with operation of the engine,
wherein each set of potential parameters includes a potential setting of a turbine of the VGT of the engine and a potential setting of an intake throttle valve (ITV) of the engine;

determining, by the controller, using a model, and based on the desired outlet pressure of the compressor, the desired temperature of the exhaust gas, and 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 the compressor and a predicted temperature of the exhaust gas, and
wherein each set of predicted values is associated with a set of potential parameters of the plurality of sets of potential parameters;

determining, by the controller, respective scores of the plurality of sets of predicted values;
selecting, by the controller and based on the respective scores of the plurality of sets of predicted values, a particular set of predicted values of the plurality of sets of predicted values; and
controlling, by the controller and based on a particular set of potential parameters of the plurality of sets of potential parameters that is associated with the particular set of predicted values, the turbine of the VGT and the ITV.
