摘要
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。仿真试验结果表明,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 TV-guided UCAV attack mobile targets on the ground,a terminal guidance law of the Self-adaption Variable Structure with Sliding Mode considering angular constraint was deduced.The proposed guidance law was operated through feedback of Une of sight angle rate,feedback of the difference between the line of sight angle and the required line of sight angle and variable structure term.To adjust proportions of the three parts reasonably,the guidance law could meet the demands of both guidance precision and impact angle.Simulation results shows that the guidance law has strong robustness to the speed change of the mobile targets on the ground and is instructive for combat operation of UCAV.
