Abstract: We numerically investigate the effect of a delayed control method on the stabilization of the dynamics of the Elet-tra storage-ring free-electron laser in Trieste (Italy). Simulations give evidence of a significant reduction of the typical large oscillations of the laser intensity. Results are compared with numerical data obtained with a derivative feedback. The possibility of an experimental implementation of the proposed method is also discussed.
