• Biodynamic Feedthrough Compensation and Experimental Results Using a Backhoe 

      Heather C. Humphreys; Book, Wayne John; Huggins, James D. (Georgia Institute of Technology, 2011-03)
      In some operator-controlled machines, motion of the controlled machine excites motion of the human operator, which is fed back into the control device, causing unwanted input and sometimes instability; this phenomenon is ...
    • Compensation for Biodynamic Feedthrough in Backhoe Operation by Cab Vibration Control 

      Humphreys, Heather C.; Huggins, James D.; Book, Wayne John (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2011-05)
      This research investigates and seeks to mitigate the undesirable effects of biodynamic feedthrough in backhoe operation. Biodynamic feedthrough occurs when motion of the controlled machine excites motion ...
    • Modeling and compensation for biodynamic feedthrough in backhoe operation 

      Humphreys, Heather Celeste (Georgia Institute of Technology, 2010-11-18)
      Biodynamic feedthrough occurs in many types of operator controlled machines where the operator is a passenger and the motion of the controlled machine excites motion of the human operator, creating unwanted feedback. It ...
    • Variable fidelity modeling as applied to trajectory optimization for a hydraulic backhoe 

      Moore, Roxanne Adele (Georgia Institute of Technology, 2009-04-08)
      Modeling, simulation, and optimization play vital roles throughout the engineering design process; however, in many design disciplines the cost of simulation is high, and designers are faced with a tradeoff between the ...
