Abstract
A crane suspended load must be transported with swing suppression and positioned in target location precisely. The control of a traveling crane is not easy because of its nonlinearily. In this paper, we present experiment results of the traveling crane positioning and swing suppression within motions of traveling/rope hoisting which is controlled by visual feedback control using a three-dimensional camera and velocity command system with variable feedback digital gains, based on digitizing the regulator controller of continuous-time system.
