Classification: CPC F | IPC F

Claim 0:
1. An apparatus for controlling a performance variable of an engine system, the apparatus comprising:
a response model circuit structured to apply a constraint to a response model that represents a relationship regarding a manipulated variable or a relationship between the performance variable and the manipulated variable; and
an optimization circuit structured to determine a target for the manipulated variable via the response model such that the target of the manipulated variable satisfies the constraint of the response model, wherein the performance variable is indicative of performance of operation of the engine system, and the manipulated variable is capable of affecting the performance variable, wherein the performance variable includes a fluid consumption value and the manipulated variable includes an engine out nitrogen oxide (EONOx) value and an in-cylinder oxygen value of the engine system, and wherein operation of the engine system is adjusted based upon the target of the manipulated variable by controlling a fuel system and an air handling system of the engine system.
