چکیده
Abstract In order to fulfill the requirement that electric linear load simulator needs improve loading accuracy by compensation method based on friction model in active situation with small load, considering influence of coulomb and maximum static friction, an improved LuGre is proposed. At same time, since effect highly nonlinear determined numerous parameters, differential evolution algorithm utilized identify dynamic parameters two steps offline. Finally, under sinusoidal signal for force command, experimental test results verify identified can accurately describe characteristics simulator.

Advances on LuGre Friction Model
LuGre friction model is an ordinary differential equation that is widely used in describing the friction phenomenon for mechanical systems. The importance of this model comes from the fact that it captures most of the friction behavior that has been observed including hysteresis. In this paper, we study some aspects related to the hysteresis behavior induced by the LuGre friction model.
