Paper Abstract

Friction is a well-known performance limitation for gimbaled EO director systems. While much research study has been directed to bearing friction, the well-known friction models in literature, being represented in time, position, and rate domain, are not amenable to most LOS jitter analysis. Furthermore the type of mission profiles to which large gimbals are subjected have received limited attention in this field of research, so the selection of an appropriate friction model is not obvious. This paper fits popular friction models to experimental data, and studies the models in frequency domain.
