Summary

This package provides a Matlab/Simulink implementation of the model for a heavy duty Diesel Engine with EGR and VGT, developed and described in Wahlström and Eriksson (2011), together with a complete parameter file. The intention of this implementation is to give researchers and engineers access to a validated model that can be used for simulation, development, and verification of new control systems. Researchers working on methodology development can use this model as a challenging reference case since it describes a highly non-linear system with non-minimum phase behaviour.

Instructions

1. Download the latest zip-archive and extract.
2. You will find a readme file, a Simulink model, a parameter file, a script and a license file.
3. To get started with the model there a MATLAB script, runSimEngine.m, that simulates the model. It produces two steps in VGT position shown in Figs 11 and 12, in Wahlström and Eriksson (2011), and generates these two figures for the eighth-order model. This MATLAB-script illustrates how the implementation can be simulated and gives examples on two step responses that have non-minimum phase behaviour, overshoot, and sign reversal.
