<P>PROBLEM TO BE SOLVED: To provide a device for controlling a sheet-fed rotary printing machine which has multiple printing units with a plurality of drive motors and which allows effective vibration damping during printing operation. <P>SOLUTION: The sheet-fed rotary printing machine 1 includes at least two electric drive motors M2, M1 acting on a gearwheel train which mechanically connects a plurality of printing units 2 to one another. The device for controlling the printing machine includes a control loop for each of the electric drive motor M2, M1 having a high-frequency control element P. At least one control loop has a low-frequency control element I supplying an output signal picked up at the control loops in a predetermined ratio T. <P>COPYRIGHT: (C)2009,JPO&INPIT |
