Second-order LuGre friction model [PDF]
A second-order LuGre friction model is presented which can be viewed as an extension of the well known LuGre friction model. This model is based on a dynamic extension, which can be seen as an extra dynamic to capture some kind of periodic motion ...

Revisiting the LuGre friction model [PDF]
In 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. The resulting model is then used to analyze stick-slip motion.

An extended LuGre friction model incorporating frictional aging [PDF]
AbstractIn this contribution, the LuGre model is extended and the effect of frictional aging is incorporated using the state variable approach. The adapted friction model is used in combination with a single‐degree‐of‐freedom oscillator to investigate the basic effects on the stick‐slip amplitude and period.

Robust Integral of Sign of Error and Neural Network Control for Servo System with Continuous Friction [PDF]
In this paper, a novel robust controller is proposed for servo mechanisms with nonlinear friction and external disturbance. First, a continuously differentiable friction model is used to represent the nonlinear friction, and neural network (NN) is ...

Identification of the Servomechanism used for micro-displacement [PDF]
Friction causes important errors in the control of small servomechanism and should be determined with precision in order to increase the system performance.

Elasto-plastic friction model: contact compliance and stiction [PDF]
The presliding displacement and stiction properties of friction models are investigated. It is found that existing single-state-variable friction models possess either stiction or presliding displacement.

Optimal control design for robust fuzzy friction compensation in a robot joint [PDF]
This paper presents a methodology for the compensation of nonlinear friction in a robot joint structure based on a fuzzy local modeling technique. To enhance the tracking performance of the robot joint, a dynamic model is derived from the local physical ...

Advances On Lugre Friction Model
LuGre friction model is an ordinary differential equation that is widely used in describing the friction phenomenon for mechanical systems. The importance of this model comes from the fact that it captures most of the friction behavior that has been observed including hysteresis.
