This content is relevant for researchers with background in control theory aiming to analyse or optimize the performance of synchronization systems. 1) Dynamic system modelling code for key components of the DESY laser-based synchronization system: piezo actuated mode-locked lasers in electro-otpical phase-locked loops (PLLs) and for piezo actuated time-of-flight stabilized optical fibres. Exemplary system parameters derived from [2] are supplied. 2) Control theoretic analysis code for robust H2-performance in terms of linear-matrix inequalities (LMIs) and integral-quadartic constraints (IQCs). In particular for linear-time-varying parametric uncertainty and time delay uncertainty. 3) Feedback controller synthesis code using IQC, LMI and nonsmooth optimization methods. Modifications to proprietary Mathworks code are not released due to licensing issues, but are described in [1] 4) Simulation code for case study results presented in [1].
