System Inversion Based Control of an Overhead Crane

IFAC Proceedings Volumes, 2000
Abstract In this paper we describe a new methodology for the control of the transient sway and of residual oscillation of the payload carried by an overhead crane. The approach consists of dampening the system by a state-feedback closed-loop and applying a noncausal system inversion in order to assure a predetermined polynomial motion law for the ...

Nonlinear optimal control of an overhead travelling crane

2009 IEEE Control Applications, (CCA) & Intelligent Control, (ISIC), 2009
This paper presents an H2-norm optimal control scheme for the three main axes of an overhead travelling crane, which guarantees both tracking of desired trajectories for the crane load and an active damping of crane load oscillations. For the model-based feedback control design series expansions are utilised to obtain an approximate solution of the ...

A precise fuzzy controller developed for overhead crane

2015 10th Asian Control Conference (ASCC), 2015
This paper presents the development of a fuzzy logic controller for load swing control of an overhead crane. What makes the proposed model complete is the quadratic derivative of state variables added to the conventional model which provides an extra weighting.

Modelling and control of vertical oscillation in overhead cranes

2015 American Control Conference (ACC), 2015
Overhead cranes are widely used in industry for lifting and moving various loads. Right before lifting a heavy load from the ground the crane bridge slightly bends, which makes the load oscillate vertically during the lifting. Vertical oscillations may introduce unnecessary stress to the crane metal structures and hoisting machinery, and thus reduce ...

Anti-swing Control of Overhead Cranes

2006 6th World Congress on Intelligent Control and Automation, 2006
In this paper a controller is designed for the overhead cranes using the recently developed parallel differential (PD) eigenevalue assignment methodology. Using this theory, classical results for LTI control design carry over to the time-varying case. The main achievement of this paper is the first implementation of a controller designed using the PD ...

Time‐optimal control of an overhead crane model

Optimal Control Applications and Methods, 1982
AbstractTime‐optimal solutions for a simple crane model have been arrived at by a number of authors using expensive analogue methods. The method described in this paper also gives time‐optimal solutions but these can be obtained using a very simple microprocessor.

Control of the double-container overhead crane

2015 34th Chinese Control Conference (CCC), 2015
Most previous work on crane control has concentrated on one-container dynamics. If the crane has two lifting ropes and two containers, then the productivity can be increased greatly, but the control problem of these cranes is more challenging because the dynamics are more complicated.

Overhead Electric Travelling Cranes

Proceedings of the Institution of Mechanical Engineers, 1937
The installation of an overhead electric crane is often left in the hands of specialist manufacturers. Plant engineers, however, need to ascertain service and performance requirements when considering an installation, and they often rebuild or modify existing cranes in order to reduce production and maintenance costs by improving the reliability of ...
