    Discrete Switching Vibration Suppression for Flexible Systems with Redundant Actuation 

    Schultz, Joshua; Ueda, Jun (Georgia Institute of Technology, 2009-07)
    If the modal response for a single degree of freedom flexible system is known, a command generation architecture can be determined which schedules on/off actuator effort such that the resulting motion will have zero ...
