Abstract
The authors propose a linear motor driven container crane system as a promising high speed and fully automated container crane system. The direct drive mechanism by the linear motor enables high acceleration or deceleration of the trolley, regardless of variable surface conditions of the suspension wheels and rail. In the proposed system, the linear motor to drive trolley is also used to control swaying motion of a hanging container.In this paper, the control system design for the proposed integrated trolley drive and swaying motion control system are discussed. The validity and the effectiveness of the proposed system were estimated by both simulation and experimental results.
