新型迅捷弹箭多源力组合控制方法

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.
