Then considering earth rotation and 6-DOF movement,the expression of absolute velocity and absolute acceleration for vehicle centroid are deduced by using transform of vector derivative.

与陆基固定垂直发射条件不同的是，潜射弹道式飞行器是在运动着的潜艇这样的动基座上进行发射的，为了保持发射时潜艇的可操纵性以及发射后使发射艇尽快离开发射位置，发射艇要有一定的速度。

The parameters optimization design model is proposed, which is based on a control model with the quasi-Euler angle, Euler angle velocity and absolute angular velocity as the feedback. The vibration-resistance parameters of the given controller are chosen as the optimization variables, and the on-off times of the engines is chosen as the optimization objective function.
