摘要:

导航、搜索和监测诸如港口、三角洲、支流和河流等动态海洋环境的能力对人类操作和自主操作的水面车辆提出了若干挑战。当面对大覆盖区域、受干扰的环境和潜在的不适合居住的情况时,人类数据汇集和监测是过度繁重和不一致的。相比之下,同样的任务可以通过配置并能够在这种环境中精确机动的自主水面车辆(ASV)来实现。在沿海和移动水域完成精确机动的两个动力因素是海流和风。在这项工作中,我们提出了新的和廉价的方法来感测这些外力,以及在这种外力的存在下精确控制ASV的方法。由此产生的平台能够部署测深和水质监测传感器。在当地湖泊和河流中的实验结果证明了所提出的方法的可行性。

英文摘要:

The ability to navigate, search, and monitor dynamic marine environments such as ports, deltas, tributaries, and rivers presents several challenges to both human operated and autonomously operated surface vehicles. Human data collection and monitoring is overly taxing and inconsistent when faced with large coverage areas, disturbed environments, and potentially uninhabitable situations. In contrast,the same missions become achievable with Autonomous Surface Vehicles (ASVs)configured and capable of accurately maneuvering in such environments. The two dynamic factors that present formidable challenges to completing precise maneuvers in coastal and moving waters are currents and winds. In this work, we present novel and inexpensive methods for sensing these external forces, together with methods for accurately controlling an ASV in the presence of such external forces. The resulting platform is capable of deploying bathymetric and water quality monitoring sensors. Experimental results in local lakes and rivers demonstrate the feasibility of the proposed approach.
