A global adaptive link position-tracking controller for robot manipulators driven by induction motors

Abstract

Abstract We present an adaptive, partial-state feedback, link position tracking controller for robot manipulators driven by induction motors. The proposed controller compensates for parametric uncertainty in the mechanical subsystem while yielding global asymptotic link position tracking. The proposed controller does not require measurement of rotor flux; furthermore, the controller does not exhibit any singularities. Preliminary experimental and simulation results are provided to illustrate the effectiveness of the proposed controller.
