An actuator includes at least one stage of turbo compressor, with an outlet for conveying gas compressed in the at least one stage of turbo compressor to at least one cooler, and a shaft for rotating the at least one stage of turbo compressor, for increasing the pressure of the gas to be supplied to the actuator. The actuator also includes a turbine and a control valve by means of which the flow of compressed gas produced by the turbo compressor to the turbine is arranged to be adjusted. A method for controlling the actuator, as well as a control system for the actuator are also described.
