Abstract
The present invention pertains to the coordination in good register of cylinders of a web-fed rotary printing press which print on a web, wherein a first cylinder printing on one side of the web is driven by a first motor and a second cylinder printing on the same side of the web is driven by a second motor and the angular position of the second cylinder is coordinated with the first cylinder in good register by a controller. At least one disturbance variable (v) is sent to a command variable (u2.Soll) for the motor controller of at least the second cylinder to compensate a register deviation (Y12) of the second cylinder from the first cylinder, which register deviation is typical of the said disturbance variable (v).
