Outline of Final Research Achievements

We developed a new wave control method for the transporting machine constructed by the suspended rope such as crane. Two approaches were investigated; the wave control of the suspended rope with pay-load near the support boundary, and the wave control of the simple pendulum system by the support acceleration. The control strategy of the suspended rope is based on the finite difference model of the rope. The condition for no reflection at the support boundary gives the control force at the boundary finite difference interval. The pendulum approach uses the wave-controlled suspended multiple simple pendulums system in the controller. The connecting condition between the real pendulum and the one in the controller brings the wave control as the support acceleration. The feedback control of the position and velocity of the support are added to the support acceleration to place the support at the other position than the original one. This control strategy was confirmed experimentally.
