    A Model Independent Observer Based Output Feedback Tracking Controller for Robotic Manipulators With Dynamical Uncertainties
    (Cambridge University Press, 2017) Zergeroğlu, Erkan; Tatlıcıoğlu, Enver; Kaleli, Egemen
    In this work, we propose the development and the corresponding stability analysis of a novel, observer-based output feedback (OFB), tracking controller for rigid-link robot manipulators. Specifically, a model-independent variable-structure-like observer in conjunction with a desired dynamic compensation technique have been utilized to remove the link velocity dependency of the controller formulation. Asymptotic stability of the observer - controller couple is then guaranteed via Lyapunov-based arguments. An adaptive controller extension is also presented to illustrate the expansiveness of the proposed scheme. Experimental studies performed on a two-link planar robot with dynamical uncertainties are included in order to demonstrate the performance and feasibility of the proposed method.

    Teleoperation With Kinematically Redundant Robot Manipulators With Sub-Task Objectives
    (Institute of Electrical and Electronics Engineers Inc., 2008) Nath, Nitendra; Tatlıcıoğlu, Enver; Dawson, Darren M.
    In this paper, control of nonlinear teleoperator systems where both the master and slave systems are kinematically redundant robot manipulators is addressed. The controller is developed under the assumption that the user and environmental input forces are unmeasurable. Lyapunovbased stability analysis is used to prove that the proposed controller yields asymptotic tracking results and ensures the coordination of the master and slave systems while satisfying a sub-task objective.
