A sheet-fed rotary printing machine includes at least two electric drive motors acting on a gearwheel train which mechanically connects a plurality of printing units to one another. A device for controlling the printing machine includes a control loop for each electric drive motor having a higher-frequency control element. At least one control loop has a low-frequency control element supplying an output signal picked up at the control loops in a predetermined ratio. A sheet-fed rotary printing machine having the device is also provided.
