摘　　要：针对三维多约束末制导问题,设计了一种实用的末制导律。结合实际应用背景,给出了三维导引建模所用地面坐标系的定义方法。为便于工程实现,选取了考虑通道耦合的三维模型,将现有文献中为提升单平面打击效果而设计的带落角和末端攻角约束的最优末制导律从二维平面扩展到三维空间。分析了俯仰通道与偏航通道之间的通道耦合对模型仿真的影响。对所设计的三维多约束末制导律进行了仿真分析。结果表明,所设计的末制导律能够准确击中目标,同时满足三维末端多约束要求。With regard to the three-dimensional multi-constraints terminal guidance problem,a practical terminal guidance law is designed.Considering the practical application background,the definition of ground coordinate system for three-dimensional guidance modeling is given.In order to facilitate engineering implementation,the three-dimensional model considering channel coupling is selected,and the optimal terminal guidance law with constraints of impact angle and terminal angle of attack designed in the existing literature to enhance the effect of single plane attack is extended from two-dimensional plane to three-dimensional space.The influence of channel coupling between the pitching channel and the yaw channel on the simulation of the model is analyzed.The designed terminal guidance law is simulated and analyzed.The results show that the designed terminal guidance law can accurately hit the target,and satisfies three-dimensional terminal multi-constraints requirements.
