Keyword:  AUV定深悬浮浮力调节系统无模型反馈控制温度与流量能耗;
Abstract: 定深悬浮是AUV实现虚拟锚泊的主要形态,一般可通过在AUV艏艉配置垂向槽道推进器或浮力调节单元实现.文中主要介绍了AUV浮力调节系统的基本原理、两种定深方式的能耗对比、无模型反馈控制策略、温度对浮力调节系统流量的影响等.湖上试验中,对AUV进行了3 m,10 m定深悬浮,试验结果表明,采用无模型反馈控制策略能够使配置浮力调节系统的AUV在合理的误差范围内实现定深,满足实际工程需要;温度对浮力调节系统的流量有一定的影响,两者大致为三次函数关系;浮力调节方式下AUV的定深悬浮较槽道推进器方式节约能源.
