Revisiting the LuGre friction model [PDF]
International audienceIn this article we first review properties of the LuGre model, including zero-slip displacement, invariance, and passivity. An extension to include velocity-dependent microdamping is also discussed.

3D projection of the LuGre friction model adapted to varying normal forces [PDF]
In this paper, we develop an adaptation of the LuGre friction model so as to allow the development of the friction force and its application in any directions on systems subjected to varying normal forces.

Experimental comparison of five friction models on the same test-bed of the micro stick-slip motion system [PDF]
The micro stick-slip motion systems, such as piezoelectric stick-slip actuators (PE-SSAs), can provide high resolution motions yet with a long motion range. In these systems, friction force plays an active role.

A Second-Order Dynamic Friction Model Compared to Commercial Stick–Slip Models
Friction has long been an important issue in multibody dynamics. Static friction models apply appropriate regularization techniques to convert the stick inequality and the non-smooth stick–slip transition of Coulomb’s approach into a continuous and ...

Effects of friction models on simulation of pneumatic cylinder [PDF]
This study examines effects of three friction models: a steady-state friction model (SS model), the LuGre model (LG model), and the revised LuGre model (RLG model) on the motion simulation accuracy of a pneumatic cylinder.

Abstract Safety and efficiency are key aspects of research and development in the automotive industry, especially in the field of safety‐critical subsystems, such as brake systems. The effect of time delay arise in brake systems, this adverse effect can cause performance degradations or make the brake system unstable.

This paper proposes a refined anti‐disturbance control method to deal with velocity output constraints and multiple disturbances. The gimbal's maximum velocity is precisely limited to a pre‐specified low range, which benefits the CMG's lifespan and performance.
