【 摘 要 】

Friction is a nonlinear phenomenon that is present in many areas of science and engineering. It has static and dynamic characteristics. This paper deals with a dynamic model of friction, namely the Dahl model. More precisely, this paper proposes a new methodology for the identification of the parameters of the Dahl model. It is shown that, in the absence of noise, the identified parameters are equal to the real ones. Numerical simulations are carried out to illustrate the identification methodology.
