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 minimized 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. 本发明涉及一种用于减小轴系、特别是涡轮机轴系中的转子振动、特别是转子振动的变化的控制系统，其中测量轴的轴承6的温度，并且将供应给轴承的油8调节到一个温度，该温度是在分配机制具有轴承的测定的温度作为输入变量时在该分配机制中针对最小转子振动的、指派的作为输出变量的温度。分配机制例如能够由转子振动的初始测量或者自学习系统提供。本发明约束了转子振动的变化。
