Abstract
A control facility for controlling a controlled system experiencing a disturbance includes a front nodal point receiving a target value and an actual value outputted by the controlled system and supplying a difference value corresponding to a difference between the target value and the actual value to a compensation circuit. The compensation circuit supplies a frequency-filtered and time-delayed signal formed as the sum of the weighted difference value and a weighted feedback signal as an input to a controller for the controlled system. The sum of a filter delay time and of first and second propagation delays is an integer multiple of the cycle duration of the disturbance, and a sum of the filter delay time and the first propagation delay is an integer multiple of the cycle duration minus a propagation time, which elapses until a change in the target value causes a change in the actual value.
