What is An Adaptive Friction Compensator for Global Tracking in Robot Manipulators about?

A novel adaptive friction compensator based on a dynamic model recently proposed in the literature is presented in this paper. The compensator ensures global position tracking when applied to an n degree of freedom robot manipulator perturbed by friction forces with only measurements of position and velocity, and all the system parameters (robot and friction model) unknown. Instrumental for the solution of the problem is the observation that friction compensation can be recasted as a disturbance rejection problem. The control signal is then designed in two steps, ÿrst a classical adaptive robot controller that (strictly) passiÿes the system, and then a relay-based outer-loop that rejects the disturbance.
