  • The maximum positional error is 20mm and the maximum sway error is 0.07 degrees in the destination position. Lots of researches and applications on the automated overhead cranes in shops have been done for some decades, but a few successful results are reported.

  • For operation of overhead crane, positioning and swing controls of a load are necessary. There is time-optimal control as feedforward control of crane. This method does not use sensors, but the trolley controlling velocity must be set using exact natural period of load swing that is beforehand estimated and the time to control swing suppression is necessary as same order of natural period.
