导弹滚动气动系数校验

在导弹研制过程中，飞行控制系统设计是基于计算得到的导弹气动参数作出的，为了提高其计算准确性，提出了一种利用飞行试验数据校验导弹滚动气动系数的方法，为此，首先建立了辨识所需的导弹滚动运动数学模型，然后提出了利用飞行试验数据对导弹滚动气动系数进行辨识计算的方法，由外干扰元法测量，而且是导弹滚动运动的重要驱动因素，因而也被作为一个未知参数的加以辨识，最后给了利用辨识结果校验滚动气动系数的方法。

CHECK OF ROLL AERODYNAMIC COEFFICIENT OF MISSILE

The design of missile's flight control system is based on aerodynamic coefficients computed. A method of checking missile's roll aerodynamic coefficients by data of flight test is raised to increase accuracy of computation. For this reason, first a mathematical model of missile's roll motion needed in identification is built. Then a method to compute roll aerodynamic coefficient by flight test data is raised. As an important drive factor in roll motion of missile, and can not be measured, external interference is also acted as an unknown coefficient to be identified.
