Vibration Control of an Overhead Crane by Elimination of the Natural Frequency Component

(Experimental Verification of Obstacle Avoidance)

Abstract

In the present situation when the importance of logistics is expanding, the automation of overhead cranes is strongly desired. The automation needs the method which is able to handle both vibration control and obstacle avoidance. In order to meet this demand, the authors proposed a systematic method for designing path of the trolley whereby the trolley and the cargo are both able to avoid obstacles while minimizing the path as well as keeping the residual vibration suppressed. In this paper, the effectiveness of the proposed method is examined by experiment.
