摘要
倾斜转弯(BTT)导弹通道间存在的控制耦合作用使得常规的双平面解耦制导律设计方法难以满足制导律设计要求。本文针对BTT导弹的三维耦合制导律设计问题,将李群理论引入到制导律设计中,将导弹速度向量中的旋转角速度用弹目视线俯仰角速度和弹目视线方位角速度来表示,同时考虑导弹制导过程中转弯尽量小以节省能量,给出一种考虑耦合项的最优三维制导律算法。通过仿真实验验证了算法的有效性。
Due to the existence of control coupling effect between channels for bank to turn(BTT)missile,the conventional two planar decoupling guidance law design approach is hard to satisfy the design requirement.In this paper,aiming at the three dimensional coupling guidance law design problem for BTT missile,Lie group theory is introduced into the coupling guidance design for air-to-air missile,where the rotational angular velocity of missile velocity vector can be expressed by the pitch angular velocity and the azimuth velocity of the line of sight between missile and target.At the meantime,considering to diminishing turning for missile during the guidance process to save energy,an optimal three-dimensional coupling guidance law is designed for BTT missile.Simulation results show that the presented guidance law is effective.
