Abstract: A system includes a controller that has a processor. The processor is configured to receive a first signal from a first oxygen sensor indicative of a first oxygen measurement and a second signal from a second oxygen sensor indicative of a second oxygen measurement. The first oxygen sensor is disposed upstream of a catalytic converter system and the second oxygen sensor is disposed downstream of the catalytic converter system. The processor is also configured to derive a plurality of oxygen storage estimates based on the first signal, the second signal, and a catalytic converter model. Each of the plurality of oxygen storage estimates represents an oxygen storage estimate for a corresponding cell of a plurality of cells in the catalytic converter system. Further, the processor is configured to derive a system oxygen storage estimate for the catalytic converter system based on the plurality of oxygen storage estimates. The processor is also configured to derive a system oxygen storage setpoint for the catalytic converter system based on the catalytic converter model. The processor is then configured to compare the system oxygen storage estimate to the system oxygen storage setpoint and apply the comparison during control of a gas engine.
