| 摘 要： | 导弹机动突防弹道设计与末制导修正能力密切相关，在可用过载与终端角度约束下，提出一种基于线偏差控制的机动突防与导引一体化设计方法。首先，建立了机动突防与导引一体化设计模型；其次，设计了可用过载与终端角度约束的虚拟导引弹道制导律；再次，提出了一种运动过载约束的螺旋机动线偏差指令信号，并设计了相对机动弹道制导律。基于指令滤波和扩张状态观测器分别解决输入受限和干扰估计问题，并基于Lyapunov稳定性理论证明了闭环系统稳定性。不同过载约束下的突防仿真结果表明，所设计的一体化方法能兼顾机动突防与精确打击需求，典型场景下对PAC 3拦截弹的单发突防成功率达到96.2%。

| Abstract: | The trajectory design of missile maneuvering penetration is closely related to the terminal guidance correction capability. Under the constraints of available overload and impact angle, an integrated design method of maneuvering penetration and guidance based on line deviation control is proposed. Firstly, the integrated design model of maneuvering penetration and guidance is established. Secondly, a virtual guidance trajectory guidance law with available overload and terminal angle constraints is designed. Thirdly, a spiral maneuvering line deviation command signal with motion overload constraint is proposed, and the relative maneuvering trajectory guidance law is designed. The problems of input constraints and interference estimation are solved respectively by using command filtering and extended state observers. The stability of closed loop system is proved based on Lyapunov stability theory. The penetration simulation results under different overload constraints show that the proposed method can meet the requirements of maneuvering penetration and precise strike, and the single penetration success rate of PAC 3 interceptor in typical scenarios reaches 96.2%. |
