Abstract

In the modern control system, especially the mechanical servo system, a suitable mechanical friction model is very important for the simulation verification of the control system or algorithm. At present, the traditional Dahl model has many defects in fitting the real friction and the simulation of the LuGre model which fits the real better is much more complicated. In this paper, a simplified LuGre model is established based on the characteristics of the Dahl model and the LuGre model. This model can be implemented with only a few simulink modules. Besides, by comparing with the simulation results of some other models, the fitting effect of the simplified model on the actual friction is closer to that of the LuGre model.
