摘要
基于Matlab数值分岔分析工具箱MATCONT对潜艇高速机动时的运动稳定性与分岔问题进行了研究。分析了潜艇重心坐标和尾升降舵角变化时的单参数分岔,搜索到系统的鞍结分岔和BP分岔点,通过垂直面非线性运动方程数值积分的动态仿真,验证了动态仿真与数值分析结果的一致性。
The problem of dynamic stability and bifurcation of submarine motion in the dive plane is examined utilizing numerical bifurcation tool box MATCONT based on Matlab .The signal parameter bifurcations analysis including submarine stern plane deflection and coordinates of submarine center of gravity are studied respectively .The saddle‐nod bifurcation and branch point are obtained ,and the stability analysis results are verified by direct numerical integration of the nonlinear equa‐tions .
