惯性／卫星制导炸弹鲁棒制导律设计

针对"惯性/卫星"制导炸弹特点和技战术要求,设计了一种带落角约束的满足L2增益指标的鲁棒制导律.制导律以控制视线角稳定为目标,选取状态变量简单,不要求炸弹速度可控,避免了求解复杂的Hamilton-Jacobi不等式,求解过程简便,便于工程应用.最后选取两种恶劣投弹环境进行了六自由度仿真,仿真结果表明:制导律对外界干扰和模型不确定性有很强的鲁棒性,并且能够很好地约束弹着角,同时较大地提高了投弹攻击区范围.

Design of Robust Guidance Law for SINS/GPS Guided Bomb

Based on the characteristic and requirements for techniques and tactics of the SINS/GPS guided bomb,a robust guidance law which meets the L2-gain and constraint of falling angle is designed.The guidance law aims to keep the line-of-sight angle stable,and it has several advantages,such as simple state variables,not requiring velocity of the bomb controllable,easy solution,and convenient engineering application.And then two worse condition simulations of 6-DOF are carried out.The results indicated that the gu...
