Congratulations to Konstantinos Tatsis for successfully defending his PhD
Konstantinos successfully defended his work on Data-Driven / Physics-Based Model Fusion for Dynamic Systems Virtualization
Konstantinos has worked on a hybrid framework for real-time monitoring of structural systems, combining monitoring information with physics-based models.
Structural Health Monitoring (SHM) aspires to ensure continuous diagnostics of a system’s health, and more importantly aims to do so while the system is in-operation, all-the-while exploiting sparse and low-cost measurements. This thesis focuses on the development of hybrid methods, which rely on vibration-based monitoring, for assessment and virtualization of dynamic systems and particular applications to wind energy infrastructure. This is a non-trivial task, due to the extreme loads these structures are subjected to and additionally due to their exposure to varying environmental and operational conditions (varying temperature, waves, mean wind characteristics). This thesis tackles this challenge via synergistically fusing physics-based models with data-driven analysis tools, for reality enhancement; or, in other words, for delivering a reliable virtual representation of the system as-is. While developed in the spirit of application for WTs, the proposed framework is an all-encompassing scheme which is transferable to further infrastructures, or general engineered systems.
His work is summarized on a number of publications, found here:
