State Estimation for the Automotive SCR Process

Zhou, Guofeng; Huusom, Jakob Kjøbsted; Jørgensen, John Bagterp

Proceedings of the 17th Nordic Process Control Workshop — 2012

Selective catalytic reduction (SCR) of NOx is a widely applied diesel engine exhaust gas aftertreatment technology. For advanced SCR process control, like model predictive control, full state information of the process is required. The ammonia coverage ratio inside the catalyst is difficult

State Estimation in the Automotive SCR DeNOx Process

on exhaust gas emissions. For advanced control, e.g. Model Predictive Control (MPC), of the SCR process, accurate state estimates are needed. We investigate the performance of the ordinary and the extended Kalman filters based on a simple first principle system model. The performance is tested through
