针对电视制导无人攻击机对地面运动目标进行攻击的问题,提出了一种带落角约束的自适应滑模变结构末制导律。该制导律通过引入基于弹目视线角速度的反馈、弹目视线角与期望落角之差的反馈及变结构项实施控制;通过合理调整三者的比例关系,可以满足制导精度和落角的双重要求。仿真实验结果表明,该制导律对地面运动目标的速率变化具有较强的鲁棒性,对无人攻击机的作战使用具有指导意义。
Aiming at the problem that the TV-guided UAS attacks on the ground moving targets, an adaptive sliding mode variable structure terminal guidance law with cornering constraints is proposed. The guidance law introduces the feedback based on the angular velocity of the projectile and the feedback and variable structure items of the difference between the expected visual angle and the expected falling angle. By properly adjusting the proportional relationship, the guidance accuracy and the dual angle of arrival can be satisfied Claim. The simulation results show that the guidance law has strong robustness to rate changes of ground moving targets and is instructive for the combat use of unmanned attack aircraft.
