Equation-free digital twins leverage Koopman theory for structural dynamics

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new digital twin framework for monitoring complex engineering structures, particularly in challenging environments with non-stationary and nonlinear dynamics. This approach utilizes Koopman operator theory and dynamic mode decomposition to reconstruct structural states in real-time without needing prior knowledge of stiffness or mass matrices. The framework was successfully validated on a floating offshore wind turbine, demonstrating high-fidelity reconstruction and a predictability horizon of approximately 1.0 second. AI

IMPACT Introduces a novel framework for real-time structural monitoring, potentially improving the resilience and efficiency of complex engineering systems.
