Overview
Recent advances have allowed for numerous applications of models to the monitoring and optimization of complex systems.
Concepts and trends such as self-adaptive systems, digital twins, and models@runtime, all benefit from a standardized model representation, that facilitates the exchange and simulation of models.
In this tutorial, we will introduce the Functional Mockup Interface (FMI) standard, and multiple tools and techniques to implement common Digital Twin features.
In particular, the following topics will be covered, complemented by a running example:
Modelling and Simulating an Incubator System (running example);
Using a Kalman Filter;
Building Functional Mockup Units with UniFMU;
Formally verifying and executing a co-simulation;
Integrating Unity visualizations with FMI co-simulation;
Collecting real-time data for monitoring applications with RabbitMQFMU.
