Abstract:
A method for active compensation of mechanical vibrations and/or deformations in industrial processing machines, comprising the steps of:providing at least one main drive in a primary axis for executing a first motion to move a mechanical machine element; combining the machine element in a secondary axis with an auxiliary drive which executes a comparably more fine-tuned second motion for so moving a machine point of the machine element that the movement of the machine point is composed of superimposed portions of the first and second motions, with the first motion moving the machine point in accordance with a predetermined desired position value, and with the second motion so compensating generated vibrations and/or a deformation of the mechanical machine element that the machine point still assumes the desired predetermined position, and ascertaining at least one state variable selected from the group consisting of acceleration, speed, and position, of the main drive and the auxiliary drive, and deriving therefrom a respective differential signal for controlling the auxiliary drive.
