Patent ID: 7559276

Claim:
A compensation device for vibrations of an angle variable in a printing material processing machine having an associated actuator for affecting the angle variable, the compensation device receiving a representative signal representative of the angle variable, and the compensation device generating an output signal for the actuator, the compensation device comprising: at least one filter having a transfer function or a sum of transfer functions having frequency parameters corresponding to vibration frequencies to be compensated, the output signal for at least one of the vibration frequencies to be compensated being a function of the representative signal passed through the at least one filter, wherein the transfer function is a Laplace transformation in the Z range wherein the transfer function is a function of 1 - b n ⁢ z - 1 1 - 2 ⁢ b n ⁢ z - 1 + z - 2 where b n =cos (ω n T), with ω n representing the angle variable and T a sampling interval.
