  • Nonlinear active control of dynamical systems
    Patent number: 7044314
    Abstract: A control system for reducing cargo pendulation. The control system calculates a correction factor and adds the correction factor for the operator input motions in addition to the motion of the platform in order to provide a reference position of the suspension point of the hoisting cable. The reference position is then provided to a tracking controller so that the crane can be forced to track the needed motions for reducing the cargo pendulation.
    Type: Grant
    Filed: October 6, 2003
    Date of Patent: May 16, 2006
    Assignee: Virginia Tech Intellectual Properties, Inc.
    Inventors: Ali Hasan Nayfeh, Dean Trischler Mook, Ryan James Henry, Zivad Navif Masoud
