DOI: 10.1109/tcst.2017.2679060

Abstract: Offshore cranes often work in harsh sea conditions. As a result, they may suffer from various external disturbances, especially the persistent and unpredictable ship motion caused by sea waves, which will introduce severe disturbances to… read more here.

recommendations! Published in 2025 at "IEEE Transactions on Industrial Informatics"

DOI: 10.1109/tii.2025.3534406

Abstract: Parameter identification in nonlinear offshore ship dynamics is crucial yet challenging, especially when measurement noise complicates the process. Differential models are particularly susceptible to large errors due to the discrete numerical differentiation of noisy data.… read more here.

DOI: 10.3389/fmars.2025.1547933

Abstract: The motion of a ship at sea is complex. This motion is affected by environmental factors such as wind, waves, and currents. These factors cause the ship’s movement to be nonlinear, dynamic, and uncertain. Such… read more here.
