Motion control of a gantry crane with a container

AIP Conference Proceedings, 2018
The 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, 2005
Considers 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.

Dynamics of spreader motion in a gantry crane

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 1998
This 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.

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), 2002
In 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 ...

Seismic Response of Gantry Cranes

2020
Gantry 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).

Gantry cranes

2003
Portal crane (1) for loading and/or unloading a ship having a multiplicity of bays for containers (10) comprising a gantry (2) with travelling gear (5) for supporting the gantry on a quay (13), a boom supported by the gantry made up of a horizontal beam (6) and a jib (7) that during loading and/or unloading is an extension of the beam, and at least one

Digital passive teleoperation of a gantry crane

2007 IEEE International Symposium on Industrial Electronics, 2007
Gantry cranes still pose a control challenge, mainly due to the problem of load swing suppression in under-actuated conditions. In the teleoperation setup, the operator-master dynamics and the transmission delay complicate the overall system design. Fortunately, the framework of passivity theory offers the necessary resources to address this problem ...

Control-based damping of elastic gantry crane vibrations

2017 22nd International Conference on Methods and Models in Automation and Robotics (MMAR), 2017
In this article control-based reduction of gantry crane elastic swinging in the trolley travel direction is concerned. As acceleration forces of the trolley are often the reason of these vibrations, they can be utilized in an appropriate damping strategy. For an elastic crane a dynamic model is derived applying the finite element method (FEM).
