Beitrag zur Regelung des Luftverhältnisses eines Ottomotors unter Berücksichtigung der Dynamik des Dreiwege-Katalysators

Universität Rostock, 2015

Abstract: For compliance with future more stringent emission standards exhaust emissions must be reduced. The thesis makes a contribution to achieve this goal by designing a new air-fuel ratio control strategy. A novel approach for modelling three-catalyst dynamics has been developed and is used in conjunction with modern control methods like nonlinear IMC (Internal Model Control), event-based control and observer-based state-feedback control to improve control performance and reduce calibration effort compared to commonly used air-fuel ratio controllers.
