A method for controlling a compression system is disclosed, specifically designed for a compression train. The compression train includes a variable speed driver unit for mechanical drive applications, a variable speed compressor with an impeller for gas compression, and an inlet guide vanes unit with an actuator. The method involves determining the initial operating state of the compressor based on operating variables, such as rotating speed, positioning angle of the inlet guide vanes, and process mass gas flow rate. The method allows minimizing an operating function of the compression train, based on constraints, to adjust the speed of the driver unit and the position of the inlet guide vanes to achieve an optimized operating state.
