Abstract
The paper presents a new describing function for a servomechanism which employs a motor driving an inertia load subject to combined Coulomb and viscous frictions, through gearing having backlash. It is shown that describing functions for various types of backlash phenomena reported in the literature can be considered as special cases of the describing function obtained in this paper.
