Design and Research of Deep sea ROV Armored Cable Winch and Active Heave Compensition Appliance
, 2009 深海ROV是一种可以在深海进行观察和作业的水下机器人。其研究和开发，对海洋环境的调查，海洋资源的钻探以及军事应用方面都具有重要的意义。深海ROV收放在深海区域收放作业时，作业环境复杂，作业深度大，如果铠缆绞车采用单卷筒结构会存在驱动装置功率过大，卷筒的转动惯量过大，载体出水的瞬间铠缆外层压入内层等问题。另外，海面的海况条件比较恶劣，支持母船受风、浪、涌、流影响而产生较大幅度的升沉运动对有缆水下机器人正常作业和收放操作有较大的影响，ROV中继器的升沉运动甚至可以造成系缆的损害而使机器人本体丢失 ...

Research on Fault Detection and Fault-tolerant Control of ROV Propulsion system
, 2007 遥控水下机器人( ROV )工作在未知的不确定的复杂海洋环境中，其机械部件和控制系统极易出现故障。推进器是ROV的动力装置，对ROV完成水下作业，顺利回收起着至关重要的作用。推进器经常受到水草、异物的干扰而损坏，同时其内部的机械和电子组件也因老化、发热、受力而容易损坏，因此推进系统故障是ROV经常发生的故障之一。故障检测是提高其推进系统可靠性的重要环节，为ROV的容错控制和紧急回收等应急措施提供科学依据。ROV的容错控制对提高ROV的可靠性和机动性有着重要的意义。 针对ROV推进系统的特点 ...
