Abstract: Systems and methods for controlling a performance variable of an engine system are provided. An apparatus includes 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. The apparatus further includes 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. The performance variable is indicative of performance of operation of the engine system and the manipulated variable is capable of affecting the performance variable. Operation of the engine system is adjusted based upon the target of the manipulated variable by controlling at least one of a fuel system or an air handling system of the engine system.

Abstract: Systems and methods for optimizing a performance variable for an engine system. The method includes applying constraints of manipulated variables as well as performance variables, mechanical constraints and other engine responses to response models. The response models each represent a piecewise linear relationship between the manipulated variables and other engine responses including performance variables and constraints. The method also comprises determining an optimal target for each of the manipulated variables by using a quasi-simplex optimization process on the response models. The optimal targets of the manipulated variables correspond to an optimal value of the performance variable.
