| 摘 要： | 该文建立了动力系统的共轭状态方程和状态方差矩阵共轭方程，以矩阵形式简明地描述了运动状态变量及其共轭变量所遵循的函数关系。状态变量与共轭变量之内积的关系式，可用于弹道偏差量计算。状态变量方差矩阵，依据它与其共轭变量方差矩阵内积之迹的关系式，用于计算多个或单个干扰对飞行器及其它动力系统统计性能的影响。

| Abstract: | This paper establishes conjugate state variable and its variance matrix equations of dynamic system, and describes functional relation between motion state variable and its conjugate variable. Their scalar product formula is used for the calculation of trajectory deviation. The relative formula of scalar product trance of variance matrixes of state variable and its conjugate one is used for calculating influence of single or many disturbances on statistical performance of vehicle and other dynamic systems. |
