摘要

摘要: 针对未知动态环境下无人水下航行器(UUV)对随机动态目标的跟踪问题, 提出了一种跟踪与避碰切换导引策略。在建立目标与UUV、障碍物与UUV相对运动学关系的基础上, 考虑UUV运动控制中航速和航向角速度的饱和约束条件, 以UUV航行安全性和跟踪精度为目标, 利用李雅普诺夫方法完成了基于视线导引切换的动态目标跟踪与避碰策略设计。对所设计的导引方法进行了仿真试验, 实现了在静态障碍物和动态障碍物2种状态下对运动目标的跟踪且满足跟踪精度的要求, 验证了所提出的跟踪与避碰切换导引策略的有效性。

Abstract: For the random dynamic target tracking problem of unmanned undersea vehicle(UUV)in unknown environment, a tracking and obstacle avoidance switching guidance strategy is proposed. The relative kinematics relation between target and UUV, as well as target and obstacle, is established, and the saturation constraint condition of speed and angular velocity in UUV motion control is taken into account. Lyapunov method is then used to complete the design of dynamic target tracking and obstacle avoidance strategy based on line of sight switching guidance in order to meet UUV navigation safety and tracking accuracy. Numerical simulation with the proposed method is carried out, and the results show that the tracking precision meets the requirement in both static and dynamic obstacle environments, verifying the correctness and feasibility of the tracking and obstacle avoidance switching guidance strategy.
