Abstract :
This paper presents a solution to the problem of global, output feedback, tracking control of uncertain robot manipulators, specifically, a desired compensation adaptation law plus a nonlinear feedback term coupled to a dynamic nonlinear filter is designed to produce global asymptotic link position tracking while compensating for parametric uncertainty and requiring only link position measurements
