Abstract

The invention relates to a control system for reducing rotor vibrations, in particular the variability thereof, in shafting, in particular turbine shafting, in which the temperature of the bearing (6) of the shaft is measured and the oil (8) supplied to the bearing is adjusted to a temperature as is assigned as the output variable in an allocation for minimised rotor vibrations with the measured temperature of the bearing as the input variable. The allocation can, for example, be provided by an initial measurement of the rotor vibrations or by a self-learning system. According to the invention, the variability of the rotor vibrations is restricted.
