Abstract: | Exhaust gas recirculation is an effective technique to reduce pollutants of diesel engines. Most actual systems use a feedforward approach, which is basically very quick, but also very sensitive to model errors and wear and requires extensive modelling work. In order to reduce both sensitivity and modelling effort, a different approach is presented, based on the use of a Lamda-sensor as measuring element, a LQG/LTR controller designed using a black box model. It is shown from empirical results that the approach delivers very good results. |
