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.
Abstract
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,inter-ceptor 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 mini-mum 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 inter-ception of interceptor.Besides,the control energy is less than that required in the serpentine ma-neuverability and square wave maneuverability penetration.
