Physics-Constrained Digital Twin
Physics-constrained digital twins are a class of technical methods that embed physical conservation laws (such as flow conservation) into the digital twin modeling process. By imposing physical law constraints, they improve system robustness against false data injection attacks while supporting inference of unobserved node states.

A study published on arXiv proposed a physics-constrained digital twin method to defend against stealthy false data injection attacks on urban pedestrian counting systems.
The digital twin absorbs counting data through learned graph localization gains and uses flow conservation residuals as the training constraint objective.
