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。
According to the characteristics of large launch vehicle structure elasticity, liquid sloshing and rigid body motion, the open or closed-loop transfer of attitude system is automatically determined by zero and pole of the transfer function of the parallel branch of platform, rate gyroscope and transverse (law) to accelerometer Function polynomial maximum coefficient terms and their values, and then by the maximum coefficient value and the computer word length mediated the best rooting coefficient K ~ *. In the end, K ~ * is used for rooting, and the open loop or closed loop transfer function of attitude system and its zero and pole are successfully obtained at one time.
