      abstract     = {For many engineering problems involving control systems,
                      finding a good working point for steady-state operation is
                      crucial. Therefore, this paper presents an application of
                      steady-state optimization with feedback on particle
                      accelerators, specifically the European X-ray free-electron
                      laser. In simulation studies, we demonstrate that feedback
                      optimization is able to reach a near-optimal steady-state
                      operation in the presence of uncertainties, even without
                      relying on a priori known model information but purely
                      data-driven through input-output measurements. Additionally,
                      we discuss the importance of including second-order
                      information in the optimization to ensure a satisfactory
                      convergence speed and propose an approximated Hessian
                      representation for problems without second-order knowledge
