摘要
以空战飞机突防为背景,基于最优控制对高速飞行器的突防技术进行研究。分别建立了高速飞行器运动模型、拦截弹运动模型和相对运动模型。为了实现突防,设计高速飞行器和拦截弹的视线角速率在某一时刻趋于无穷大,并将此作为终端约束;考虑高速飞行器控制能量最小,建立性能指标函数,基于最优控制理论设计突防制导律。仿真结果表明,采用最优突防制导律的高速飞行器能够突破防御弹的拦截,且控制能量要小于蛇形机动和方波机动突防策略所需的控制能量。
In the background of air combat,the high-speed aircraft’s penetration technology based on the optimal control theory is studied.In this paper,the high-speed aircraft motion model,interceptor motion model and relative motion model are established respectively.In order to achieve the penetration,the rate of line of sight angle between high-speed aircraft and interceptor is designed to become infinity at a certain moment,which is used as the terminal constraint.Considering the minimum energy control of the high-speed aircraft,the performance index function is established.Based on the optimal control theory,a penetration guidance law is designed.The simulation results show that high-speed aircraft which adopts the optimal penetration guidance law can penetrate the interception of interceptor.Besides,the control energy is less than that required in the serpentine maneuverability and square wave maneuverability penetration.
