Abstract
A digital twin is an evolving virtual model that mirrors an individual physical asset throughout its lifecycle. An asset-specific model is a powerful tool to underpin intelligent automation and drive key decisions. The formulations and methods of dynamic data-driven application systems (DDDAS) have a key role to play in the tasks of inference, assimilation, prediction, control, and planning that enable the digital twin paradigm. Of particular importance is a tight feedback loop between models and data, which has long been a central concept in DDDAS. This keynote talk presents an approach to create, update, and deploy data-driven physics-based digital twins. We demonstrate the approach through the development of a structural digital twin for a custom-built unmanned aerial vehicle.
