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.

Abstract: An apparatus for angle-based localization of a position on a surface of an object includes an orientation sensor configured to be arranged in a known relationship relative to a position, to be identified, on a surface of an object at at least one measurement time and to capture angle information items in respect of the current orientation thereof at the measurement time, and a programmable device, with a processor and a memory, wherein the memory contains instructions and at least one assignment prescription for the object with the surface, where angle information items are assigned associated positions on the surface of the object, and wherein the instructions cause the programmable device to receive the angle information items captured at the measurement time by the orientation sensor and to establish the position to be identified by an assignment to the captured angle information items on the basis of the assignment prescription.

Abstract: A method for supplying an excitation current to an excitation winding of a rotor of a three-phase generator of a system for producing a three-phase alternating voltage to be fed into a power network. A pulsed excitation current is supplied to the excitation winding if a rotational frequency of the rotor deviates from a network frequency of the power network.
