Friction phenomenon can be described as two parts which are pre-sliding and sliding regions. In motion of<br/> the sliding region, friction forces depend on the velocity of the system and are known as Coulomb, stick-slip,<br/> stribeck effect and viscous friction. The pre-sliding region, which is before breakaway, depends on the<br/> position of the system. The motion of friction in the sliding region can be described as the LuGre model. But<br/> the pre-sliding motion of friction, which has hysteresis characteristics in general, is not known widely.<br/> Therefore, an improved friction model, which can describe the motion of friction in the pre-sliding region, is<br/> proposed in this paper. And simulation and experimental results show the effectiveness of the proposed<br/> friction model for precise tracking control systems.
