- Abstract
- Input shaping has been a very effective control method for reducing payload swing in industrial
bridge and gantry cranes. However, conventional input shapers often degrade performance when
applied to tower cranes because of the nonlinear coupled dynamics between rotational and radial
motions in tower cranes. To alleviate this problem, a new input shaper for tower cranes is
developed by means of dynamic modeling, analysis and optimization. This work investigates the
tower crane dynamics along with parameters of the tower crane varied. A performance index for
input shaper design is proposed so as to reduce the coupled residual vibration of a tower crane
using only rotational motion of tower crane. The proposed new input shaper is verified to be
effective through simulations and experiments.
