The paper investigates a nonlinear vibration mitigation strategy of a variable length
pendulum subjected to a harmonic external excitation. A nonlinear absorber in a form of a tri …

The dynamic characteristics of 3-D overhead cranes with double-pendulum effect are
complex, which makes the controller design particularly challenging. Besides, in actual …

This paper presents a new control scheme based on model reference command shaping
(MRCS) for an overhead crane, with double-pendulum mechanism effects. The approach …

Most of the existing anti-swing control methods treat the crane as a single pendulum system
with fixed rope length. In this paper, considering the varying rope length, the dynamic model …

Specific payload shape and hoisting mechanism will transform the crane to a complex
double pendulum system with a distributed mass beams (DMB), which makes its control …

This paper proposes an event-triggered global sliding mode based anti-sway control for
offshore container cranes. Its main objective is to guarantee the robust tracking performance …

The paper proposes and investigates nonlinear vibrations mitigation strategies of an
externally excited pendulum. This problem is highly relevant to the crane's payload …

As a kind of convenient and practical oscillation suppression method, the open-loop
controllers are widely utilized in the control of actual cranes, yet most of them need to be …

This paper aims to explain the design of a novel time-varying sliding mode control of
variable parameter (VP-TVSMC), which can effectively solve the anti-swing and positioning …

As underactuated systems, tower cranes are usually regarded as single-pendulum systems
in modeling. However, in many situations, such as when the mass of the payload and the …
