Abstract
A friction identification method includes: measuring a relation between a driving force and a position of a driven object; identifying a parameter of a position-dependent friction model based on a relation between a driving force and a position of the driven object; measuring a relation between a driving force and a displacement of the driven object from a position at which a motion direction is reversed; identifying a parameter of a displacement-dependent friction model; measuring a relation between a driving force and a velocity of the driven object; identifying a parameter of a velocity-dependent friction model; measuring a relation between a driving force and an acceleration of the driven object; and identifying a parameter of an acceleration-dependent friction model.
