| 摘 要： | 利用大地磁场具有方向性的特点,设计了末端修正迫弹程控飞行控制系统,并提出了一种程控飞行控制算法.通过分析弹丸在飞行过程中所受的力和力矩,建立了弹丸的飞行动力学模型,并利用飞行试验的遥测数据对系统气动与控制参数进行了分析辨识,利用辨识结果进一步验证了程控系统的可行性和数学模型的正确性.

| Abstract: | Based on the direction of geomagnetic field,the program control system in certain guided mor- tar and the control algorithm are designed.By analyzing the forces and moments acted on the guided mor- tar during flight,the trajectory model is established.The results of radar data are used to validate and check the correctness of the trajectory model and the control system. |
