Abstract: For ammonia coverage of urea-SCR systems, whose state is not measurable, a reduced-order observer method based on Input-to-state Stability (ISS) is proposed. The errors of sensor measurement including temperature, exhaust gas flow rate are considered as additional disturbance inputs. The observer is designed in order that the error dynamics is input-to-state stable, and the guideline for selecting the controller parameters is given. The transient performance of the proposed observer is tested on an validated enDYNA diesel model with urea-SCR aftertreatment systems. Comparing with common mechanism observer, the proposed observer has better performance.

Key words: artificial intelligence, reduced-order observer, nonlinear, input-to-state stability(ISS), ammonia coverage estimator
