摘      要：Control parameter optimization is an efficient way to improve the endurance of underwater gliders(UGs),which influences their gliding efficiency and energy *** paper analyzes the optimal matching between the net buoyancy and the pitching angle and proposes a segmented control strategy of *** optimization of this strategy is established based on the gliding range model of UG,which is solved based on the approximate model,and the variations of the optimal control parameters with the hotel load are *** optimization results indicate that the segmented control strategy can significantly increase the gliding range when the optimal matching between the net buoyancy and the pitching angle is reached,and the increase rate is influenced by the hotel *** gliding range of the underwater glider can be increased by 10.47%at a hotel load of 0.5 *** optimal matching analysis adopted in this study can be applied to other UGs to realize endurance improvement.
