摘　　要：运用 Fossen 方法将鱼雷空间运动方程进行了矢量化,得到了高度简练的基于鱼雷体坐标系和惯性坐标系下的运动方程的矢量化,并给出了矢量参数矩阵的性质。在此基础上分析了鱼雷在开环和闭环控制条件下的稳定性,说明了鱼雷运动方程矢量化的实用性。A set of high concise vectored kinematical equations both in body coordinates and inertia coordinates of torpedo in 6 degrees of freedom motion is obtained in this paper by means of the Fossen way of deducing equations of moving body,and the character of coefficient matrix is given.Based on the vectored equations,the stabilities of the torpedo under the open loop and closed loop control system are analyzed,which testify the practicability of the vectored equations.
