摘　　要：在固定翼鸭舵式双旋制导迫击炮弹飞行控制中,为提高落点精度,通过调节鸭舵的控制力矢量方向实现横法向过载控制,需要建立鸭舵的滚转姿态与横法向过载的对应模型实现炮弹的飞行准确控制。针对上述问题,提出了预测落点与比例导引两种制导算法,做为双旋弹的制导飞行控制。通过搭建控制系统的实物仿真模型,模拟双旋弹的双旋运动过程,对预测落点与比例导引制导算法进行了对比分析,通过仿真验证了两种制导算法都可以实现双旋的弹道修正.预测落点算法可以用于全弹道修正精度,但是修正过程中弹体振动较大,比例导引算法只能进行下降段弹道修正,但修正过程较为平滑,控制稳定性较好。因此为实现双旋弹的弹道修正,需要上升段采用预测落点算法,下降段采用比例导引制导算法。In the flight control of dual-spin guided mortar, the control force vector of the fixed wing canards is ad- justed to achieve horizontal and vertical overload control, so it is necessary to establish the corresponding model be- tween canards roll attitude and the overload to achieve the flight eontrol of the mortar. In view of the above problems, the paper presented two guidancing algorithms of prediction of impact and proportional navigation as the control algo- rithm of the dual-spin projectile. The Dual-spin motion process of the dual-spin projectile was simulated by establis- hing the physical simulation model of control system. Predictive and proportional navigation guidance algorithms were analyzed and contrasted, and the fact that two algorithms based on the control force veetor can achieve trajectory cor- rection was verified by simulation, the prediction algorithm can be used for rise and fall ballistic, but body vibration was more serious, while the proportional navigation algorithm can only be used for the fall ballistic, hut the correction process was smoother and the control stability was better. In order to realize the dual spin projectile trajectory correction, the prediction algorithm was used for the rise ballistic, and the proportional navigation guidance algorithm was used for the fall ballistic.
