Abstract

The invention concerns a closed-loop controller for influencing one or more control devices in a fluid-carrying line of a turbomachine, in particular of a steam turbine, with one input each for upper and lower limits of the manipulated variable. According to the invention, the output value of a controlled following integrator, increased by a set value ( DELTA ) is applied to the controller input for the upper limit of the manipulated variable, and the output value of the above-mentioned integrator, or another controlled following one, decreased by a set value ( DELTA ), is applied to the controller input for the lower limit of the manipulated variable. This makes rapid changes in the manipulated variable possible in the small-signal range, while the (preset) correcting rate limitation remains in effect unchanged in the large-signal range.
