New submissions to the thesis/dissertation collections are added automatically as they are received from the Graduate School. Currently, the Graduate School deposits all theses and dissertations from a given semester after the official graduation date. This means that there may be up to a 4 month delay in the appearance of a given thesis/dissertation in DRUM.

More information is available at Theses and Dissertations at University of Maryland Libraries.

    SIMULTANEOUS ATTITUDE AND MANIPULATOR CONTROL FOR DETUMBLING COUPLED SATELLITES WITH APPENDAGES
    (2019) Dillow, Barrett Edward; Akin, David L; Aerospace Engineering; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    Satellite servicing is of increasing interest in industry. Thousands of satellites, functional and not, are tumbling and would likely need to have their attitude stabilized for servicing or orbital change maneuvers. Further, a well-studied method for achieving capture between a servicer and a client satellite is with a robotic manipulator. This research presents a set of algorithms to achieve attitude stabilisation while reducing client appendage motion. A nonlinear quaternion feedback controller is presented; its stability proven and its utility discussed. A method of client appendage mode motion is presented. Finally a manipulator control algorithm to reduce client appendage motion is presented. These methods can be employed to increase the potential number of non-cooperative serviceable satellites.
