| 摘 要： | 为实现舰船纵摇和升沉运动的解耦,基于保结构同谱流算法,提出一种解耦变换的寻找方法,将寻找解耦变换的非线性问题转化为Sylvester方程的求解问题,并利用矩阵Kronecker积的相关知识快速找到解耦变换.基于水池实验获得的纵向运动数据进行的数值实验仿真结果表明该方法确实可行.

| Abstract: | To realize the ship vertical motion decoupling,a method to find out decoupling transforms was proposed based on structure preserving isospectral flows(SPIF),which converting nonlinear problem in the process of finding out decoupling transforms into the solution of Sylvester equation,and matrix Kronecker product knowledge was used for finding decoupling transforms out quickly.Numerical experiments based on pool experiment data show the feasibility of the proposed method. |
