Anti-sway control for overhead crane

2007 International Conference on Control, Automation and Systems, 2007
The models of overhead crane system have been studied in many regulation methods; hence bring about the variation parameter. However, there are have the similar conjecture of angular velocity (thetas dot) in the mathematics models of pendulum system. The angular velocity can be deduced to be zero to perform the simply system as the linear equation form.

Funnel control for overhead crane model

PAMM, 2018
AbstractWe consider an overhead crane whose control variables are the length of the rope and force/velocity at the gantry. The output consists of the position of the load. The objective is to design a closed‐loop tracking controller which also takes into account the transient behavior. First we show that this system has no well‐defined relative degree,

Fuzzy logic controller for overhead cranes

Engineering Computations, 2006
PurposeTo propose a new method for controlling the overhead crane systems based on the theory of fuzzy logic with a reduced number of rules than has appeared before in the literature. The proposed fuzzy logic controller (FLC) can be implemented to move the overhead crane along a desired path while ensuring that the payload is swing free at the end of ...

Disturbance rejection control for overhead cranes

2017 IEEE International Conference on Real-time Computing and Robotics (RCAR), 2017
In 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 ...

Electrical aspects of overhead travelling cranes

Journal of the Institution of Electrical Engineers - Part I: General, 1948
The paper is intended to serve as a guide to engineers who desire to install electrically operated lifting equipment over an area of factory, warehouse, stockyard or power plant. Emphasis is laid on performance rather than design, and mention of many of the smaller items of crane equipment has purposely been omitted. The paper discusses the information

Dynamic Model of an Overhead Crane

In this thesis a novel spatial model of an overhead crane was developed. The model includes: bridge, trolley, driving and follower wheels for the bridge and trolley, drum, cable, and the payload. The model accounts for the winding/unwinding of the cable around the drum as the payload is raised/lowered. The cable and the payload were considered as rigid
