Research on Guidance Command Generation Algorithm of Fastest Angle Maneuvering Attack

针对现代空战的特点,根据战机飞行动力学,对时间最优情况下的最速角度机动攻击导引指令生成进行了研究。将最速角度指向机动导引控制问题视为受终端状态、过程以及控制约束的多约束优化问题,通过引入惩罚函数将多约束优化问题转化为无约束优化问题,然后利用共轭梯度法寻优得到导引指令,给出了最速角度指向机动导引指令生成的具体算法,最终通过仿真证明了所提算法的有效性。

According to the characteristic of modern air combat,A new guidance command generation algorithm of fastest angle maneuvering attack is investigated based on dynamics of the fighter. The generation of guidance command is treated as an optimization problem with multi-constrains of terminal states constraints,process constraints and control constrains. It is transform into a non-constraint optimization problem. Then the conjugate gradient method is used to search for the command. The detailed steps of the algorithm are presented. The simulation result shows that the algorithm presents is effective.
