Systems and methods adjusting for aftertreatment system condition

An electronic control unit, comprising:

• a processor operatively coupled to a memory, wherein the processor is programmed to execute instructions on the memory to:
• obtain one or more engine signals representative of operations of an engine;
• execute a model to derive an estimated catalyst emission based on the one or more engine signals and on an expected catalyst degradation;
• obtain one or more catalyst signals representative of catalyst performance;
• generate an adaptation signal configured to improve accuracy of the model based on the one or more catalyst signals;
• and
• apply the adaptation signal and the estimated catalyst emission to generate an engine control signal.

One or more non-transitory computer-readable media storing one or more processor-executable instructions wherein the one or more instructions, when executed by a processor of a controller, cause acts to be performed comprising:

• obtaining one or more engine signals representative of operations of an engine;
• executing a model to derive an estimated catalyst emission based on the one or more engine signals and on an expected catalyst degradation;
• obtaining one or more catalyst signals representative of catalyst performance;
• generating an adaptation signal configured to improve accuracy of the model based on the one or more catalyst signals;
• and
• applying the adaptation signal and the estimated catalyst emission to generate an engine control signal.
