在支撑分布式协同BTT航弹的研制过程中,航向机动时受协调支路影响滚转出现晃动。针对该问题,利用航向无法阶跃机动的特点,提出圆弧路径规划及与之适应的非线性制导律优化算法,并利用Lyapunov稳定性理论对算法的稳定性进行分析,同时提出适用于集群协同BTT航弹的双椭圆航路安全越界及过点判断策略,最后,半实物仿真验证上述方法的有效性。结果表明航向机动时姿态比较平稳,滚转角抖振幅度降低了一个数量级。

In the process of designing of BTT aerial bomb supporting distributed and collaborative combat, the roll jitter problem is caused by the influence of the coordinated branch during heading maneuver. To solve the problem, arc route planning and the corresponding nonlinear guidance optimization algorithm are proposed by taking advantage of the fact that the course cannot be stepped maneuver. Lyapunov stability theory is used to analyze the stability of the algorithm. At the same time, a double elliptical route safety cross-border and the over-point judgment strategy are proposed, which is suitable for the cluster coordinated BTT aerial bomb. Finally, the effectiveness of the proposed method is verified by the semi-physical simulation test. The results show that the attitude is relatively stable during maneuvering, and the roll angle jitter amplitude is reduced by an order of magnitude.
