1. A system comprising:
a fuel system having a first response time;
an air handling system having a second response time, the second response time being slower than the first response time;
an aftertreatment system having a third response time, the third response time being slower than the second response time; and
a controller configured to:
interpret a first basis variable set for the fuel system, a second basis variable set for the air handling system, and a third basis variable set for the aftertreatment system;
determine a first reference value set in response to the first basis variable set at a rate based on the first response time;
determine a second reference value set in response to the second basis variable set at a rate based on the second response time;
determine a third reference value set in response to the third basis variable set at a rate based on the third response time; and
provide one or more control commands to each of the fuel system, the air handling system, and the aftertreatment system in response to the first reference value set, the second reference value set, and the third reference value set, respectively.
