Abstract

In a method for moving a machine element of an automation machine with separately controlled drive shafts moving in a common direction, a first controller receives a first desired control variable, which is filtered using a filter having a frequency-dependent transfer function. In one embodiment, first desired control variable represents an overall movement of a machine element. A difference is determined between the filtered first desired variable and a first actual variable, and the difference is supplied as a desired control variable to the second controller for controlling the movement of the second drive shaft. In another embodiment, the filtered first desired variable and a second desired variable are added to form a sum, and a difference between the formed sum and the first actual variable is supplied as a desired control variable to the second controller for controlling the movement of the second drive shaft.
