Adaptive Sliding-Mode Control of an Offshore Container Crane With Unknown Disturbances

IEEE/ASME transactions on mechatronics, 2019
In this paper, an adaptive sliding-mode control (ASMC) for offshore container cranes that load/unload containers from a mega container ship to a smaller vessel is investigated.

Dynamic analysis and time optimal anti-swing control of double pendulum bridge crane with distributed mass beams

, 2020
The existing anti-swing control of crane is mostly used for the single pendulum system, but in practical application, specific payload shape and hoisting mechanism will induce to complex double pendulum dynamics.

Scheduling Yard Cranes Considering Crane Interference

2011
Automated stacking cranes form the heart of modern container terminals. Hence, their productivity has a major influence on the performance of the terminal. In the first part of this paper, the yard crane scheduling problem and its practical relevance from the point of view of the Container Terminal Altenwerder (CTA) in Hamburg, Germany, is described ...

Adaptive sway reduction for tower crane systems with varying cable lengths

, 2020
For practical underactuated tower cranes, vertical payload motion is always involved to increase the working efficiency, making the control problem more complex.

An adaptive tracking control method with swing suppression for 4-DOF tower crane systems

Mechanical systems and signal processing, 2019
As an efficient transportation tool, a tower crane is widely used in construction sites. To improve the working efficiency, some automatic control methods have been proposed for tower crane systems, including some open loop methods, such as input shaping

Nonlinear Antiswing Control for Crane Systems With Double-Pendulum Swing Effects and Uncertain Parameters: Design and Experiments

IEEE Transactions on Automation Science and Engineering, 2018
In practical applications, industrial cranes may exhibit double-pendulum swing effects, due to many factors, such as large payload scales and non-negligible hook masses.
