Abstract
In this paper, the adaptive compensation of Coulomb friction is considered where the Coulomb friction coefficient is unknown but can be time-varying with a known period. Detailed stability analysis is given with some demonstrative simulation results. The major contributions of this paper is a periodic adaptive control law for friction compensation in nonlinear electromechanical systems not satisfying local and global Lipschitz condition
