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 ...

Active Anti-Sway Control of Multi-Ropes Gantry Cranes with Scale Model Test

Annual Conference of the IEEE Industrial Electronics Society, 2023
Gantry cranes are widely used for transporting containers in industry. Lacking in model tests and practical control strategy, the problem that the load suffers swaying due to disturbances such as wind and inertia still exists for spatial multi-rope ...

DDPG-Based PID Optimal Controller for Position and Sway Angle of RTGC

International Conference on Control, Automation and Systems, 2023
Increasing global trade requires fast and accurate container transfers by minimizing positional errors and swing angles on the Rubber Tyred Gantry Crane (RTGC) at the container yard causing that the optimization of the controller is a necessity ...
