Reconstruction of State Space of the Trolley-Load Dynamic System in Overhead or Gantry Cranes

  • A full-state observer was designed to obtain swing angle,swing angle-velocity and the other system state variables.The differences of the observed outputs of the state observer from those of the trolley-load system are calculated first,and these differences are sent to the feedback input after adjusted by a gain vector.The coordinates of the observer’s pole are the key parameters affecting observation time when other parameters are known.To reconstruct the state variables precisely,the observer’s pole is placed on the negative real-axis in the complex plane,and in the flat range on the curves of observation time vs.coordinates of the observer’s pole.
