Method for compensating for an oscillation in a printing press

A method for compensating for an oscillation having a frequency spectrum with a number of discrete frequency components in a printing press, which comprises the steps of:

• analyzing the frequency spectrum and determining frequency components of the oscillation;
• classifying individual frequency components into a first group including integer multiples of a machine frequency ωM and into a second group including non-integer multiples of the machine frequency ωM;
• determining a first counter torque for compensating only frequency components of the first group and introducing the first counter torque into the printing press;
• operating the printing press;
• while the printing press is operating and the first counter torque is applied to the printing press, measuring amplitudes of the second group of frequency components;
• and
• determining second counter torques for compensating frequency components of the second group from said measurements and additionally introducing the second counter torques into the printing press.
