潜艇舱室进水限制线支持向量机绘制方法研究

On Emergency Prognosis Simulation of Submarine Passing through Ocean Front

潜艇水下舱室进水可挽回的初始状态存在限制,针对现行绘制进水限制线"试凑"法的不足,提出一种新的潜艇水下舱室进水安全操纵限制线SVM绘制方法。该方法的主要步骤包括:收集训练样本;样本向量描述;选择核函数训练样本,求解分类决策数学模型;在潜艇水下操纵安全界限图中标绘分类曲线。基于相同有限样本,运用SVM绘制方法与"试凑"法同时绘制某型潜艇水下舱室进水限制线。选取样本集以外的初始点开展了挽回仿真,检验了两种限制线的分类有效性,结果表明,SVM方法绘制的限制线分类性能优于传统的"试凑"法。

There is a limitation on the initial state of the water inflow in submarine cabin. Aiming at the shortcomings of the current "try-and-error" method of drawing flooding limit lines, a new SVM drawing method of safe operation limit lines for the water inflow in submarine is proposed. The main steps of this method include: collecting training samples;sample vector description;selecting kernel function training samples to solve the classification decision mathematical model;plotting the classification curve in the submarine underwater maneuvering limit map. Based on the same limited sample, the SVM drawing method and the "trial and error" method were used to draw the flooding limit line of one class of Submarine. The initial point outside the sample set was selected to carry out a recovery simulation experiment to test the effectiveness of the classification of the two limit lines. The results show that the classification performance of the limit line drawn through the SVM method is better than the traditional "try and make" method.
