非常规机动操纵要求的计算

首先推导了飞机运动的逆动力学模型，为使问题具有一般性，采用了刚体运动模型，其中力方程建立在风轴系中，力矩方程建立在体轴系中，并且已知气动力模型，其次，由于飞行轨变地标位置（ｘ，ｙ，ｚ）的形式给出，因此构造了一种基于坐标位置的算法，当给定坐标值后，即可据此对逆问题进行求解并得出相应的操纵要求，最后以一种非常规机动动作为例进行了逆仿真，得出了操纵要求。

用特征根构造变系数线性最佳控制

本文研究单输入n阶常系数线性系统满足二次型指标(积分区间有限,终点给定为(o,…o)) 的最佳控制。所得结果使用户无需解Riccati方程,也不要用数值法解出两点边值问题,仅由这个两点边值问题的特征根即可构造变系数线性最佳控制。这个结果既适于低价(n=1,2,3)时用来写出变系数线性最佳控制的一般表达式(17)—(19),也适于高阶时用计算机计算,其程序已用FORTRAN-Ⅳ在AD三TAMAX-186机上实现。     

A holistic approach to SIM platform and its application to early-warning satellite system

This study proposes a new simulation platform named Simulation Integrated Management (SIM) for the analysis of parallel and distributed systems. The platform eases the process of designing and testing both applications and architectures. The main characteristics of SIM are flexibility, scalability, and expandability. To improve the efficiency of project development, new models of early-warning satellite system were designed based on the SIM platform. Finally, through a series of experiments, the correctness of SIM platform and the aforementioned early-warning satellite models was validated, and the systematical analyses for the orbital determination precision of the ballistic missile during its entire flight process were presented, as well as the deviation of the launch/landing point. Furthermore, the causes of deviation and prevention methods will be fully explained. The simulation platform and the models will lay the foundations for further validations of autonomy technology in space attack-defense architecture research.     

Orbit determination and prediction of GEO satellite of BeiDou during repositioning maneuver

In order to establish a continuous GEO satellite orbit during repositioning maneuvers, a suitable maneuver force model has been established associated with an optimal orbit determination method and strategy. A continuous increasing acceleration is established by constructing a constant force that is equivalent to the pulse force, with the mass of the satellite decreasing throughout maneuver. This acceleration can be added to other accelerations, such as solar radiation, to obtain the continuous acceleration of the satellite. The orbit determination method and strategy are illuminated, with subsequent assessment of the orbit being determined and predicted accordingly. The orbit of the GEO satellite during repositioning maneuver can be determined and predicted by using C-Band pseudo-range observations of the BeiDou GEO satellite with COSPAR ID 2010-001A in 2011 and 2012. The results indicate that observations before maneuver do affect orbit determination and prediction, and should therefore be selected appropriately. A more precise orbit and prediction can be obtained compared to common short arc methods when observations starting 1 day prior the maneuver and 2 h after the maneuver are adopted in POD (Precise Orbit Determination). The achieved URE (User Range Error) under non-consideration of satellite clock errors is better than 2 m within the first 2 h after maneuver, and less than 3 m for further 2 h of orbit prediction.
