Abstract
In large-scale crane systems, open-loop control is generally used as one of practical control method for anti-sway control. The typical control method in open-loop control accelerates the supporting part of the crane constant, and the acceleration time is restricted to natural vibration period of the crane. The purpose of this study is to reduce the acceleration time. Our strategy is to make a short term for damping control between other two constant acceleration terms. We confirmed that about 20% of the acceleration time can be cut by this control method.
