EXPERIMENTAL COMPARISON OF DIFFERENT FRICTION MODELS FOR ACCURATE LOW-VELOCITY TRACKING

Low velocity friction causes positioning and contouring errors such as the quadrant glitch in machine tool table systems. Numerous comprehensive friction models are described in literature. A comparison of these models with respect to feedforward friction compensation is not yet available: only comparisons with the Coulomb friction model are available. This paper compares four friction models, one static model and three comprehensive dynamic models, with respect to their friction compensation ability.
