摘要

新罕布什尔大学一直在研究一种用于开放海洋水产养殖网圈的自动空运系统的可行性。本研究提出一种基于自动反馈控制的深度控制原型装置。自动化系统旨在简化空气举升的操作,并减少地面连接的数量,这些连接的耐候性很差。该系统通过控制压载舱和环境水之间的压差的压力调节器来驱动,从而通过控制进出压载舱的质量流量来控制整体浮力。控制装置在梯形逻辑上运行,并允许用户使用人机界面(HMI)系统和相关的图形用户界面(GUI)与之交互。通过样机试验,确定了PID和砰砰控制的气升系统是控制气升系统的有效手段。控制器驱动的硬件允许精确的深度设定值以及实时误差和干扰抑制。

An automated airlift system for open ocean aquaculture
The University of New Hampshire has been investigating the feasibility of an automated airlift system for open ocean aquaculture net pens. This research proposes a prototype depth control device based upon automatic feedback control. The automated system aims to simplify operation of the airlift, as well as reduce the number of surface connections which weather poorly. The system is actuated via pressure regulators controlling the pressure differential between a ballast chamber and the ambient water, thus controlling overall buoyancy by controlling the mass flow rate into (or from) the chamber. The control device operates on ladder logic and allows the users to interact with it using a Human-Machine Interface (HMI) system and an associated Graphical User Interface (GUI). Through experimental prototype testing, it is determined that a PID and bang-bang controlled airlift system is an effective means of controlling the airlift system. The controller actuated hardware allows for precise depth set point values as well as real-time error and disturbance rejection.
