Abstract
A system, method, and apparatus for predicting and controlling tailpipe NOx conversion and ammonia slip based on degradation of an aftertreatment system. The aftertreatment system is coupled to a controller. The controller can be configured to retrieve, from a memory, a model of a catalyst of the aftertreatment system. The model can be generated based on at least historical data from at least one sensor upstream of the catalyst and at least one sensor downstream of the catalyst. The controller predicts, using the model, a first value to be sensed by the sensor upstream of the catalyst and a second value to be sensed by the sensor downstream of the catalyst. The controller controls reductant dosing from a doser based on the predicted second value.
