Abstract
This paper presents a control strategy for an automotive selective catalytic reduction (SCR) system, for which the feedback is based on a NOx sensor measurement. This NOx sensor is cross-sensitive to NH3, which is critical for control purposes: a study of the closed-loop dynamics is performed which permits to calibrate the control strategy. Experimental results illustrate the performance of the proposed approach.
