Compensation of cylinder vibration in printing material processing machines

摘要

A compensation device ( 9 ) for vibrations of an angle variable in a printing material processing machine ( 1 ) having an associated actuator ( 6 ) which acts on the angle variable, the compensation device ( 9 ) receiving a signal representative of the angle variable characteristic, and the compensation device ( 9 ) generating an output signal for the actuator ( 6 ) is disclosed. The compensation device ( 9 ) has at least one filter ( 13 ) in the form of a transfer function or a sum of transfer functions whose frequency parameters correspond to the vibration frequencies to be compensated, through whose effect the output signal of the compensation device ( 9 ) is obtained from the signal at at least one of the discrete frequencies to be compensated.
