Prototypical Control for the Digital Twin of Aircraft Environmental Control System

A digital twin of the overall aircraft EnvironmentalControl System is being developed as part of TheMa4HERA, alarge European Research Initiative. It shall supportverification and validation by virtually demonstrating thebehavior of the complete system in various conditions. Tothis end, also a prototypical control scheme needs to bedeveloped so that a dynamic simulation through completeflight missions is enabled. The prototypical control schemeis tuned using a simplified version of the Digital Twinwhich focuses on robustness and fast computation time,while making it robust enough to be stable when used withthe high-fidelity Digital Twin. An already stable andworking controller for simulating the detailed DigitalTwin, provides a significant gain of time, allowing forimmediate preliminary results on both steady-state andtransient system behaviors. This paper describes the basemodel of the Digital Twin and the methodology used todesign the prototypical control architecture.
