Control Strategy and Implemention of a Quick Pressure Device for Underwater Escape

Abstract

Abstract:

A fast compression experimental system by water injection was proposed by means of analyzing the working characteristics of the fast floating escape from deep sea, where fuzzy control was applied. The fuzzy control strategy was chosen by analyzing the influences of pneumatic control valve with serious hysteresis and nonlinearity of the control system based on AMEsim simulation platform. A precise control of the fast compression was process by water injection was achieved by building onshore debugging platform, and the feasibility of fast compression was proved by water injection to achieve fast floating escape from deep sea.

Key words: underwater escape, fast compression by water injection, fuzzy control, hysteresis system

摘要：

针对深海快速上浮脱险的工作要求，提出了一种基于模糊控制的快速注水加压实验系统。基于AMESim仿真平台，研究了带有严重迟滞非线性的先导式气动流量调节阀对系统控制性能的影响，优选了模糊控制策略。通过构建的陆上调试平台，采用模糊控制法，实现了快速注水加压过程的精确控制，验证了通过快速注水加压实现深海快速上浮脱险的可行性。
