Dynamic output-feedback stabilization of uncertain linear dynamics via digital twins

This work presents a digital twin framework for output-feedback stabilization and parameter identification in uncertain dynamical systems.

A virtual model evolves in parallel with the physical process, assimilating measurement data in real time.

By design, the digital twin reconstructs the system state and generates a stabilizing feedback, while model parameters are simultaneously inferred from data of the controlled dynamics using a Bayesian approach.

Numerical results for the coupled physical-virtual dynamics demonstrate how digital twins can act jointly as observers, parameter estimators, and control agents, ensuring robust performance under uncertainty.
