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