Optimisation of Air Management Control in Turbocharger Diesel Engines (OCAD)

FEDER-CICYT DPI2001-3106-C02-02.

The main objective of this project is to design a control algorithm that will allow to control jointly the turbocharger pressure and the exhaust fumes re-circulation in turbocharger Diesel engines. At the moment, the turbocharger and the exhaust fumes re-circulation are regulated by independent loop, even though they are strongly coupled as a system. This creates many problems.
In order to attain the fixed objective, suitable predictive and multi-variable control techniques will be applied as required by the problem. In the development phase of the project, modelling techniques will be used and later tested in test benches to be validated and finally tuned. In addition, the need to use sensors and/or alternative actuators to improve the system control will be analysed.
An inter-disciplinary group of researchers from the Universidad Politécnica de Valencia has been formed to work on this project and ensure its objectives. Researchers come from two complementary knowledge areas: on the one hand, the DMMT group contributes with its great experience in Diesel engines research and design, on the other hand, the CPOH group provides the essential knowledge in control to solve the problem. Both groups have the adequate equipment and facilities to realise the project.
