Robust adaptive tracking control with L/sub 2/-gain disturbance attenuation for electrically-driven robot manipulators

Abstract

This paper develops a new Lyapunov recursive design for the robust adaptive tracking control problem of rigid-link electrically-driven robot manipulators with uncertainty. The novelty is in the strategy to construct such a Lyapunov function recursively that ensures not only stability of a tracking error system but also an L/sub 2/-gain constraint for the tracking performance.
