Robust Control Design for the Mass-Damper Type Anti-Sway System

In the previous studies, we suggested a new type of swing motion control system for the crane system in which a small auxiliary mass is installed on the spreader. The actuator reacting against the auxiliary mass applies inertial control forces to the spreader of the container crane to reduce the swing motion in the desired manner. In the papers, to identify the usefulness and validity of the proposed system, we applied several control strategies. In the results, good control performance and valuable results had been achieved. In this paper, we evaluate and check the system in the point of more real application. For an example, the transportation process of RTG to handle the cargos is considered. In this case, undesirable sway motion might be occurred. To suppress this motion, a pursueable strategy (approach) is introduced. And, it will be shown that the proposed control strategy is useful and it can be easily applicable to the real world
