Method and device for controlling at least one rotating component of a printing press

A method for controlling a speed of at least one rotating component of at least one printing couple of a printing press, wherein the at least one rotating component (01) of the at least one printing couple, and having a rotational speed which is variable over time, is controlled, in accordance with a target value for a temperature (θb) which represents the component temperature of the at least one rotating component at a desired rotational speed, using a temperature control device having a response time in which the temperature control device can vary the temperature of the rotating component (20, 21), and wherein at least one drive (32) of an assembly of the printing press is at least one of regulated and controlled on the basis of a target value for said rotational speed of said at least one rotating component, which rotational speed target value, (ntarget), is prescribed by a control level (31) and with regard to a rotational speed (n) that is to be maintained, characterized in that, during at least an operating phase (I) of said at least one rotating component, in which operating phase, said rotational speed of said at least one rotating component is varying over time, the rotational speed target value of said at least one rotating component (ntarget), as prescribed by the control level (31), is corrected by taking into account at least one precontrol element of a path and control model of the temperature control device and relating to one of running time and time constants (VLZ) of the temperature control device, which path and control model characterizes the response time of the temperature control device (20, 21), and by then using the resulting corrected rotational speed target value for the rotational speed (n′target) of the at least one rotating component as a prescribed value for controlling the rotational speed (n) of the drive for the at least one rotating component (32) wherein the path and control model predicts the physical operation of the temperature control device and corrects the rotational speed target value to the corrected rotational target value in accordance with the response time of the temperature control device as characterized by the path and control model.
