Tianjin Adar Ltd.

Special application to offshore marine crane control environment is a big challenge. On the one hand, similar to land-based crane equipment UNDERACTUATED various marine crane model, you need to control the price of marine cranes swinging loads generated during transport to ensure its accuracy and transport efficiency. [Jada Industry and Trade to recommend star product - marine crane ship goods] Introduction: where, Parker et al using command shaping techniques, pitching rotation of the crane jib is controlled and verified on a small-scale experiment platform. McKenna et al pitching arm and hull motion for modeling marine cranes, and through the feedforward and feedback control strategy aspects combine to suppress unilateral upward load swing. Masoud, who used the time lag position feedback control method, through the manipulation of two-dimensional pitch and swing arm to reduce the load swing angle. Sandia National Laboratories designed a control scheme based on multi-sensor data fusion, by controlling the movement of the crane movement to compensate for hull marine cranes, better suppressed swing load. This approach TACS system in the U.S. Navy conducted experiments to get better control effect. Subsequently, Schaub et al for this control scheme has been further improved.
