Abstract

Lightweight design of production machines results in a problematically high inclination of vibration. Existing control techniques can avoid those vibrations based on the knowledge of the instantaneous system behavior, which is highly nonlinear and dependent on the machine’s pose. One possibility is to calculate the machine behavior using a model of the machine on the control device. By this, additional and expensive sensors in the machine structure are avoided but it requires a fast and efficient algorithm of model-based system behavior identification calculated online on the control device. In this paper, we describe a new approach for model-based system behavior calculation on the control device for the vibration reduction. Emphasizes lies on the integration of the method into the engineering process, which is shown in the fact that standard models out of the engineering process are used. The approaches and benefits of the technique are shown on a two-axes machine structure.
