| 摘 要： | 根据大型运载火箭的结构弹性,液体晃动和刚体运动的特性,由平台、速率陀螺和横(法)向加速度表等并联支路的传递函数零、极点,自动确定姿态系统开环或闭环传递函数多项式的最大系数项及其值,再由最大系数值和所用计算机的字长介出最佳压根系数K~*。最后用K~*进行压根,一次成功地求出姿态系统开环或闭环传递函数及其零、极点。

| Abstract: | According to the characteristics of the construction elasticity, liquid shaking and upright body moving of a launch vehicle, and by zeroes and poles of the transfer function of every parallel branch for platform, rate gyroscope and horizontal or vertical acce-lerometer etc., it determines automatically the biggest coefficient item of multi-item formula of the open-loop or closed-loop transfer function for the attitude system, and the value of this item. Then, it solves an optimal coefficient K* for pressing roots, by the biggest value and the byte length of the computer to be used. And finally, it presses the roots by K* and successfully solves in no time the open-loop or closed-loop transfer function for the attitude system, and the zeroes and poles of the transfer function. |
