Disturbance rejection control for overhead cranes
2017 IEEE International Conference on Real-time Computing and Robotics (RCAR), 2017In the presence of persistent perturbations in both unactuated and actuated dynamics of crane systems, this paper designs an observer-based robust control method that achieves the objective of trolley positioning and cargo swing suppression. The system dynamics are transformed into a quasi-chain-of-integrators form, based on which a reduced-order ...

Optimal control of overhead cranes
Control Engineering Practice, 1995Abstract A nonlinear dynamic model of an overhead crane which represents simultaneous travel, traverse, and hoisting/lowering motions is considered. Nonlinear feedback forms of control are studied, and numerical results are obtained in such a way that specified boundary conditions and the functional constraints for the states and controls are ...

Intelligent control of overhead gantry cranes
2009 6th International Symposium on Mechatronics and its Applications, 2009Overhead gantry crane systems have been integral part of many heavy industrial applications needing material handling and transportation. This can easily be seen in emerging countries growing rapidly. Single force control input applied to crane moves it to a desired position but also triggers undesired swing on the payload which makes it an interesting

The switching algorithm for the control of overhead crane
Neural Computing and Applications, 2006This paper presents the fuzzy logic based method to control the trolley cranes. The information, including the position of trolley, load swing and the differences between the present and previous signals, are applied to derive the proper power to drive the trolley.

Electromechanical modelling of overhead cranes
International Journal of Systems Science, 1992A non-linear electromechanical model describing the dynamical behaviour of overhead cranes is presented. The model takes into consideration the non-linear dependence of the load sway on transients of driving motors during voltage disturbances and start-ups.

Energy Efficiency of Overhead Cranes
IFAC Proceedings Volumes, 2014Abstract Energy efficiency is firstly considered into the control of overhead cranes. Based on the model of crane system, energy consumption as well as operational safety is formulated in an optimal control problem. The optimal control is used to search optimal trajectories of velocity and acceleration for minimizing energy consumption.

The switching fuzzy controller of the overhead crane system
Proceedings of the 2004 IEEE International Conference on Control Applications, 2004., 2005This work presents the switching method for the fuzzy control of the overhead cranes. One uses the information of the trolley position, load swing and their differentiations to derive the proper control signal. The switching fuzzy algorithm to overcome the condition of deadzone is especially investigated in This work.
