Experimental Study on Anti-Swing Control Strategy of Portal Crane

In this research, the anti-swing control strategy of portal crane for handing operation in port was studied by experiments. Firstly, the anti-swing control strategy of portal crane was designed, and the important parameter range of the control strategy was preliminarily analysed based on simulations. Secondly, the inclination measurement system of wire rope was developed, whose reliability was verified by experiments. Thirdly, by using the anti-swing control system, the anti-swing strategy could be joined to crane control system. Finally, through optimizing the anti-swing control coefficient in the field test, the working efficiency of the portal crane could be greatly improved under handling condition, where the final rotating position was appointed. Meanwhile, the driver operations and other performances of crane were not affected. The experimental works proved that satisfactory results could be achieved with the anti-swing control strategy.
