水下滑翔机中尺度过程空间采样运动仿真

Marine mesoscale processes, including vortices, fronts, and internal waves, are a class of important dynamic processes in the ocean that have a significant influence on global climate change and the transport of marine energy, heat, and materials. The observation and investigation of such processes also have important practical significance in the field of marine resources, organism exploration, and military domains. Underwater gliders have recently become important devices for observing mesoscale processes. “Petrel-Ⅱ,” a type of autonomous underwater glider, is considered the main focus of this study. First, a dynamics model is established based on the momentum and angular momentum theorems. Simulink is then used to confirm the feasibility of the proposed model. According to the simulation results, the proposed dynamic model can realize motion simulation well. Finally, based on the different requirements for the detection of several mesoscale processes, different sampling motion schemes are presented, and a motion simulation of spatial sampling is provided. This study could provide a reference and optimization parameters for future practical observations and applications.
