Aiming at the problem of complex cluster constraints in the process of master slave AUV (Autonomous Underwater Vehicle) formation transformation and tracking in the wave environment, it is proposed to introduce the model predictive control (MPC) method to normalize a variety of complex constraints in the process of group formation navigation, unify the kinematic model and dynamic model, and introduce the normalized constraint...

The structural hydrodynamic response of longline aquaculture facilities under the influence of waves and currents is complex. Studying the hydrodynamic characteristics of this aquaculture structure in complex sea environments can contribute to sustainable offshore aquaculture solutions. Thus, we established a numerical model using AquaSim2.18, a proven and effective finite element hydrodynamic software for analyzing the maximu...

Cargo transfer vessels (CTVs) are designed to transfer cargo from a floating production storage and offloading (FPSO) unit into conventional tankers. The dynamic positioning system allows the CTV to maintain a safe position relative to the FPSO unit using a flexible cargo transmission pipe, and the CTV tows the tanker during operating conditions. The operation mode can be considered a synchronization tracking control problem....
