Gantry crane control: A simulation case study
2013 2nd Experiment@ International Conference (exp.at'13), 2013A simulation teaching experiment to control a gantry crane system is proposed. The control is performed both in open-loop and closed-loop. The open-loop control is based on the Posicast feedforward technique and the closed-loop control uses a two-degrees of freedom configuration.

Rest to rest movement of a crane’s swinging load, at the bottom end of a cable, by moving a speed-limited gantry trolley at the top, involves resolving the apparently conflicting demands of exact load positioning and active swing damping. If system parameters are unknown beforehand, best existing strategies offer only asymptotic solutions. The proposed

Regulation strategy of an Ultracapacitor storage model for a gantry crane
IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, 2013This paper presents, for a system consisting of a gantry crane, the regulation strategy of an Ultracapacitor (UC) based storage system, and its performance test using a simulated model of the system A model for the study of the accumulation of electrical energy in Ultracapacitors was presented. This model was validated by comparing the simulation model

Dynamics of spreader motion in a gantry crane
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 1998This paper illustrates the steps necessary to model the dynamics of a model rubber-tyred gantry (RTG) crane as used in container-handling operations. Various modelling criteria are discussed with the emphasis placed on the importance of non-linear coupling between the chosen system coordinates.

Seismic Response of Gantry Cranes
2020Gantry cranes are customized to meet specific requirements at a facility. Due to their unique configuration, prescriptive design, based on empirical rules, cannot be justified. Gantry cranes have some brittle elements (joints and connections) and some ductile elements (steel beams and columns).

Motion control of a gantry crane with a container
AIP Conference Proceedings, 2018The transportation of a container by a gantry crane in a given time from one point of space to another is considered. The system is at rest at the end of the motion. A maximum admissible speed is taken into account. The control force is found using either the Pontryagin maximum principle or the generalized Gauss principle.

Nonlinear feedback control of a gantry crane
Proceedings of 1995 American Control Conference - ACC'95, 2005Considers a nonlinear dynamical model for a gantry crane to design a control input that transports a load along a specified transport trajectory in such a way that the load angle oscillation is suppressed as quickly as possible. A nonlinear tracking controller for the load position and velocity is designed that gives guaranteed performance.

Lumped Mass Models of Gantry Cranes
2019This chapter discusses the mathematical modeling of gantry crane systems, considering the subsystems of a crane to be rigid bodies. Such a formulation does not reflect the deflections within the individual parts of the crane but only considers their rigid body movements and results in a lumped mass model (LMM).

Online learning control of a gantry crane
Proceedings of the 2000 IEEE International Symposium on Intelligent Control. Held jointly with the 8th IEEE Mediterranean Conference on Control and Automation (Cat. No.00CH37147), 2002In many industrial control applications, different controller structures and parameters should be used for different operating scenarios. These changes can be due to plant or environmental variations. The classical control approaches are either the use of some sort of gain scheduling to cover different operation modes, or to adapt the controller ...
