摘要
目前弹道导弹组合中制导飞行段存在多种调姿时序要求。为了协调各种要求,提出了一种弹道导弹中段飞行调姿规划方法。首先,采用四元数姿态控制方法推导了最小时间和给定时间条件下的姿态角速度指令以及程序四元数,求出四元数姿态控制偏差量作为最优调姿时序规划的基础;然后,确定了中制导各阶段的时序约束条件,建立了优化中段飞行调姿时序的规划模型;最后,采用随机方向搜索法对仿真算例进行了优化计算。仿真结果表明,调姿规划模型可以实现中段飞行姿态时序的协调。
At present,there are many posture adjusting time sequence requirements in the combined midcourse guidance phase of ballistic missile. In order to coordinate various requirements,a planning method of pose adjusting in the midcourse flight of ballistic missile was put forward. Firstly,the pose angular velocity and pose quaternion instructions were derived by using the pose quaternion control method,and the pose control dispersion was calculated,which were used to the foundation of the optimal time sequence planning of pose adjusting. Then,the time sequence constraints of midcourse guidance phase were made certain,and the planning model to optimize the pose adjusting was established. The optimization calculation of the simulation example was carried out by using the random direction searching method. Simulation results show that the model can realize the coordination of midcourse flight pose time sequence.
