A variable detail model simulation methodology for cyber-physical systems

This publication is about simulating cyber-physical models with varying levels of detail, how to structure the models to make this possible and how to design the submodels required. A structured method is posed to select which signals of the model to use for the structure and how to determine the different parts of the models to abstract away when varying the detail of sub-models. This method is applied to two examples based on a lab setup available. One example shows hard limits due to encoder processing, the other example shows the effects of simplified dynamic models. The method is effective in both examples and shows a clear trade-off between accuracy and performance.
