潜艇近水面航行的CFD闭环控制仿真研究
Study on CFD-based closed-loop control simulation for submarine near-surface navigation
摘要
Abstract
Aiming at the problem that traditional underwater vehicles used dynamic models for motion control simulation,which failed to accurately consider the complexity of fluid forces such as turbulence,friction,and flow separation,a closed-loop control simulation method combining computational fluid dynamics(CFD)and proportion integration differentiation(PID)control algorithms was proposed.First,the Navier-Stokes(N-S)equations and PID control equations were used to calculate the fluid forces and moments as well as the control forces and moments at the current moment.Then,the forces and moments were transmitted to the six-degree-of-freedom motion equations of the underwater vehicle to simulate the motion response,aiming to improve the accuracy of motion control simulation for submarines navigating near the water surface.Research results show that this method effectively reduces the heave and pitch responses of the submarine,with the reduction in motion response reaching up to 84%under high sea states,which could provide theoretical support for submarine design and operation,and offer guidance for control strategies during actual navigation.关键词
