Anti-sway fixed-order control of bridge cranes with varying rope length

2017 IEEE International Conference on Mechatronics (ICM), 2017
In this paper, a gain-scheduling control law is proposed to attenuate the oscillations in overhead cranes induced by manual operations, for different values of the rope length. To take into account the practical limits in controller implementation, a fixed-order controller is tuned, by enforcing certain robustness and performance constraints.

Anti-sway control of variable rope length container crane based on phase plane trajectory planning

Journal of Vibration and Control, 2023
An overhead crane system is a complex time-varying system if it includes simultaneous hoisting and moving operations. To address the problem that time-varying systems usually have no exact analytical solution, an anti-swing method based on linear approximation of the phase plane trajectory is proposed.

Experimental study on vibration control for rope-sway of elevator of high-rise building

Proceedings of the 2002 American Control Conference (IEEE Cat. No.CH37301), 2003
This study presents a synthesis method of a nonstationary optimal controller with a time-varying criterion function for reducing the vibration of a time-varying object such as moving ropes of elevators and cranes. For the time-varying object a stationary optimal control has little effective on reducing vibration.

Vibration Control of Rope-Sway of Elevator for High-Rise Building

Volume 6B: 18th Biennial Conference on Mechanical Vibration and Noise, 2001
Abstract This study presents a synthesis method of a nonstationary optimal controller with a time-varying criterion function for reducing vibration of a time-varying object such as rope of elevator and crane. For time-varying object a stationary optimal control is little effective in reducing vibration.

Sway control of rotary crane using straight transfer transformation method considering the variation of rope length

Proceedings of the 41st SICE Annual Conference. SICE 2002., 2003
This paper presents a method to control the sway of a rotary crane by using a straight transfer transformation (STT) model. The STT model is built and its parameters are geometrically derived. Considering the variation of the rope length, optimal control of a rotary crane is solved using an optimization method of Davidon-Fletcher-Powell (DFP) so that ...
