A soundproof device 30 for a duct 15 e.g. an intake duct for a compressor (fig.1, 11) of a gas turbine (fig.1, 13), comprising a first sound absorbing material 31 disposed on one side a an outer wall

Methods and systems for surge control in a compressor system. A recirculation valve position may be actuated in response to identified conditions of potential surge, determined from a compressor map. Recirculation valve position may be controlled by calculating distance of current operating state to a surge line and using proportional integral control to manage the distance. Compressor speed command may be derated in response to identified surge, determined from one of speed fluctuations of the compressor speed, or variance of a compressor speed tracking error.
