Energy Consumption Modeling for Underwater Gliders Considering Ocean Currents and Seawater Density Variation

Energy management is a critical and challenging factor required for efficient and safe operation of underwater gliders (UGs), and the energy consumption model (ECM) is indispensable. In this paper, a more complete ECM of UGs is established, which considers ocean currents, seawater density variation,...
