Abstract

In this paper an adaptive partial state feedback controller is designed for a rigid-link electrically-driven (RLED) robot manipulator. The controller is based on structural knowledge of the electromechanical dynamics of the RLED robot and measurements of link position and electrical winding current in each of the link actuators. The proposed controller is designed to adapt for parametric uncertainty in the electromechanical dynamics while utilizing a dynamic filter to generate velocity tracking error information. The design of the controller, adaptation laws, and the pseudo-velocity filter are done through a Lyapunov approach, the benefit of which is that at the end of the design procedure the controller can be mathematically shown to produce semiglobal asymptotic link position tracking.
