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 various timing requirements for guidance flight in ballistic missile combinations. In order to coordinate all kinds of requirements, a mid-flight ballistic attitude adjustment planning method was proposed. Firstly, the quaternion attitude control method is used to derive the attitude angular velocity instruction and the quaternion of program under the minimum time and the given time, and the quaternion attitude control deviation is obtained as the basis of the optimal attitude adjustment sequence planning. Secondly, The timing constraints of each phase of the guidance are determined, and a planning model for optimizing the timing of the mid-level flight attitude is established. Finally, a random directional search method is used to optimize the simulation study. The simulation results show that the attitude adjustment planning model can achieve the coordination of the mid-flight attitude.
