摘要:

为大幅度提高导弹的超大角度机动能力, 提出一种新型迅捷弹箭多源力组合控制方法。首先通过在传统直接力/气动力复合控制敏捷导弹尾部加装一类柔性可控伞, 设计一种新型弹箭构型, 然后基于合理假设将柔性可控伞简化为作用在敏捷导弹尾部的可控柔性力, 并给出可控柔性力大小、方向、驱动机构动态响应特性的量化描述方法, 进而建立铅垂平面内引入可控柔性力的动力学模型, 最后针对强耦合、强不确定性、快时变性、强非线性的多输入多输出系统, 设计柔性力/直接力/气动力复合控制律, 实现了新型弹箭的迅捷转向。通过仿真验证了所提方法的合理性和有效性, 并与传统敏捷导弹进行仿真对比, 验证了所提方法有利于提高超大角度机动能力。

Abstract:

A multi-source force control method for novel agile projectiles is proposed to improve the large angle maneuverability of the missiles. Firstly, the geometric configuration of the novel agile projectiles is designed by adding a type of flexible and controllable parachute to the tail of traditional reaction-jet and aerodynamic compound control agile missiles. Then, based on reasonable assumptions, the flexible and controllable parachute is simplified as a controllable flexible force acting on the tail of agile missiles. A quantitative description method for the magnitude, direction, and dynamic response characteristics of the controllable flexible force is provided. Furthermore, a dynamic model introducing controllable flexible force in the vertical plane is established. Finally, for the multiple input multiple output system with strong coupling/strong uncertainty/fast time variability, and strong nonlinearity, the flexible force, reaction-jet and aerodynamic compound control law is designed to achieve the agile turn of the novel projectiles. The rationality and effectiveness of the proposed method is verified through simulation, and compared with traditional agile missiles, it is verified that the proposed method is beneficial for improving the large angle maneuverability.

Key words: missile, agile turn, flexible and controllable parachute, controllable flexible force, sliding mode control, extended state observer (ESB)
