    Daisy: A Large Flexible Space Structure Testbed for Advanced Control Experiments

    Daisy is an experimental testbed facility at the University of Toronto’s Institute for Aerospace Studies (UTIAS) whose dynamics are meant to emulate those of a real large flexible space structure (LFSS); see F...

    Forward Kinematics of a 3-DOF Variable-Geometry-Truss Manipulator

    The forward kinematics of an octahedral type variable-geometry truss manipulator is presented. The manipulator is comprised of two stacked octahedral trusses. The intersection of the octahedra consist of 3 lin...

    Dynamics of flexible space vehicles with active attitude control

    The implications of flexible appendages on the attitude dynamics of a space vehicle are examined in general terms. Two families of natural vibration modes, referred to as ‘constrained’ and ‘unconstrained’, are...

    Liapunov stability of spinning satellites with long flexible appendages

    The equations of motion are derived for the case of a spinning satellite which has a central rigid body, and long flexible appendages which are nominally in the spin plane. The ‘major-axis theorem’ is found to...
