Abstract

KELLY, R.. Enhancement to the LuGre model for global description of friction phenomena. Lat. Am. appl. res. [online]. 2004, vol.34, n.3, pp.173-177. ISSN 0327-0793.

The LuGre model of friction -a bristle based model- predicts important friction phenomena useful for control of mechanical systems. This model accurately describes the behavior of control systems for small initial conditions. This paper proposes a simple but fundamental modification of the model in order to improve the reliability in a global sense. This improvement increases the comprehension of experimental evidences in control of mechanisms.
