Optimal Robust Distributed Control Towards Attosecond Synchronization Systems

192 Seiten, Dissertation Technische Universität Hamburg (2025), Softcover, A5

Zusammenfassung / Abstract

Synchronization systems in free-electron laser facilities enable frontier experiments on (sub)molecular matter. This work comprises a control theoretic analysis of such systems, explicitly taking into account their inherent nature as distributed time-delay systems. Robust stability and performance guarantees against uncertain parameters are incorporated, adding to the complexity of optimal controller design for such systems. Practical time and frequency domain synthesis methods are presented for this generally intractable problem and developed further. In a case study, the methods are evaluated on a real laser-based synchronization system at European XFEL, demonstrating attosecond performance.
