Abstract

Model based simulation is increasingly used to create and test virtual system prototypes and is becoming an integral part of every vehicle development program. To be an effective tool, model based control system development and testing should be done with extreme care and with proper understanding of model limitations and assumptions. An erroneous model implementation canlead to erroneous design conclusions resulting in a very undesirable effect on vehicle development process and timing. Similarly, a model implementation that requires an unreasonable amount of time for est up and execution will have few willing customers. This paper shows that model structure and implementation play a critical role in simulation performance and suggests that there may be certain "preferred" application-specific model implementation. Specifically, it is demonstrated that the same functionality implemented in different ways can lead to different simulation performance. This is done using hybrid system examples that are often used and are necessary to describe an internal combustion engine and its control system.
