摘要
[目的]针对自主水下航行器(AUV)执行通信任务的隐蔽性要求,提出一种带折叠天线的AUV近水面通信模式。[方法]基于切片理论对规则波的波浪干扰力进行预报,建立AUV五自由度近水面运动方程;结合视线法(LOS)和PID控制器,开展AUV本体的波浪跟随控制仿真研究。[结果]仿真结果表明,空间循迹运动的法向跟踪稳定精度为0.2476m,波浪跟随运动的垂向跟踪稳定精度为0.2326m,控制效果较好。同时,统计分析发现,波高和波频对控制效果影响显著,波高和波频越大,控制效果越差。[结论]所做研究验证了AUV近水面波浪跟随运动的可行性,可为高隐蔽实时通信等提供理论模型支撑。
[Objective]To address the covert communication requirements of autonomous underwater vehicles(AUVs),this study proposes a near-surface communication mode equipped with a foldable antenna.[Methods]Utilizing strip theory to predict the wave forces of regular waves,a five-degree-of-freedom motion equation for the AUV near the water surface is established.Simulation studies on wave-following control of the AUV are conducted using the line-of-sight(LOS)method and PID controllers.[Results]Simulation results demonstrate that the normal tracking stability accuracy of the spatial trajectory is 0.2476 m,and the vertical tracking stability precision of wave-following motion is 0.2326 m,indicating satisfactory control performance.Statistical analysis reveals that wave height and frequency significantly impact control effectiveness;larger wave height and frequency result in poorer control outcomes.[Conclusion]This study validates the feasibility of wave-following motion for AUVs near the water surface,providing theoretical support for high-covert real-time communication applications.
