A NONLINEAR OBSERVER FOR FLEXIBLE JOINT ROBOTS
Abstract
This paper presents the design of a kind of semiglobal nonlinear observers for flexible joint robots which needs the measurements of the positions of each motor rotor and link. For the proposed observer, the error equation is locally exponentially stable about the origin, with a region of convergence which may be arbitrarily enlarged by a suitable choice of the observer gain. The results are illustrated by simulation examples.
