Friction compensation based on LuGre model
Proceedings of the 45th IEEE Conference on Decision and Control, 2006We consider a tracking problem for mechanical systems. It is assumed that feedback controller is designed neglecting some disturbances, which could be approximately modeled by a dynamic LuGre friction model. We are interested to derive an additive observer-based compensator to annihilate or reduce the influence of such a disturbance.

A LuGre Tire Friction Model With Exact Aggregate Dynamics
Vehicle System Dynamics, 2004The LuGre dynamic point contact friction model for the two-dimensional translation of a body on a surface has been used in the past to derive a model for the friction forces and moments at the contact patch of a tire. The resulting tire friction model is distributed, described by a set of partial differential equations. Several approximations have been

Modeling of a Planar Microrobot Using LuGre Friction Model
Volume 8: Dynamic Systems and Control, Parts A and B, 2010Microrobots design and manufacturing has been one of interesting fields in robotics in recent years. Various legged designs have been proposed in the literature. All designs rely on friction for locomotion. In this paper the dynamic model of a planar two-legged microrobot is presented using LuGre friction model.

On Lugre Friction Model to Mitigate Nonideal Vibrations
Journal of Computational and Nonlinear Dynamics, 2009In this paper, a nonideal mechanical system with the LuGre friction damping model is considered. The mechanical model of the system is an oscillator not necessarily linear connected with an unbalanced motor of excitation with limited power supply. The control of motion and the attenuation of the Sommerfeld effect of the considered nonideal system are ...

An investigation of a novel LuGre-based friction force model
Mechanism and Machine Theory, 2021Abstract The LuGre friction force models are amongst the most popular and powerful approaches to treat frictional contact in modeling, simulation and control of mechanical systems. However, these friction force models have some numerical difficulties related to physical inconstancies, when the systems under analysis include frictional contacts with ...

Friction Identification Based Upon the LuGre and Maxwell Slip Models
IEEE Transactions on Control Systems Technology, 2005The problem of friction identification within the presliding and sliding regimes is addressed and three identification methods, designated as the LuGre (LG) method, the nonlinear regression (NLR) method, and dynamic nonlinear regression with direct application of the excitation (DNLRX) method, are postulated.

On the LuGre model and friction-induced hysteresis
2006 American Control Conference, 2006In this paper, we study hysteresis induced by friction in a simple mass-spring system and then in a dc servo motor experimental setup. The experimental setup is modeled and simulated using the Dahl, LuGre, and Maxwell-slip friction models. Comparison of the experimental and simulation results reveals that the LuGre model provides the best model of the ...

A Modification of the LuGre Friction Model for Potential Energy
2020 59th Annual Conference of the Society of Instrument and Control Engineers of Japan (SICE), 2020Friction is a familiar phenomenon, but it is difficult to accurately describe its behavior. Many models have been proposed to represent friction. The representative one is the LuGre model, which approximates friction with bristle spring and damper. The LuGre model dissipates not all of the kinetic energy, but conserves part of it as potential energy in

The Friction Model of Dynamic-Wheel Model Based on LuGre Model
Applied Mechanics and Materials, 2014With the development of the simulator and the increase of vehicle model simulation frequency, the ring tire models become the research focus. The ring model considers the physical characteristics of the tire, thus it can more accurately describe the tire force transmission.
