潜艇垂直面操纵运动模型误差仿真分析

研究潜艇操纵运动性能优化问题,潜艇垂直面运动模型是潜艇垂直面操纵运动稳定性的基础,运动模型建立的精确与否将直接影响潜艇操纵运动精确性和实时性。为此,以某型潜艇为研究对象,编制潜艇垂直面线性与非线性操纵运动仿真程序,通过仿真并与实艇试验数据比较,分析了两种操纵运动模型的仿真误差,结果表明潜艇垂直面操纵运动模型中的非线性项的影响非常小,由于解算线性模型的速度要比非线性模型快得多,证明垂直面线性操纵运动精确性对垂直面内的自动操纵有很大提高,说明垂直面线性操纵运动模型很有使用价值。

Simulated Analysis of Error in Submarine Vertical Linear and Non-linear Manoeuvre Movement Model

Submarine vertical manoeuvre movement model is the foundation of submarine vertical manoeuvre movement,the fitness of model can affect the accuracy and real-time of simulation.Taking a certain submarine as the research object,this paper gave the simulated programme and obtained some data.After comparing with the real test data and analyzing the simulated error in the two models,this paper finds that the influence of non-linear part in submarine vertical manoeuvre movement model was very little,because the speed of calculating linear model is much faster than calculating non-linear model,so the vertical linear manoeuvre movement model can do a lot benefit to vertical automatic manoeuvre,and compare with the non-linear model,the linear model is more valuable.
