Guidance law with impact angle constraints based on extended disturbance observer

  • 摘要: 针对导弹拦截机动目标时要求限制终端攻击角度的问题,提出了一种基于扩张干扰观测器(EDO)的有限时间收敛制导律.考虑拦截时弹目相对运动关系,将导弹速度的时变、未知的运动目标加速度视为扰动,采用EDO对干扰进行实时的观测和补偿.通过引入快速跟踪微分器解决制导律中所需期望视线角速率无法直接获取的问题.同时,在制导律性能分析中引入了滑模捕捉能力的概念,分别对不同攻击场景和不同运动形式的机动目标进行拦截仿真,结果表明该制导律有良好的制导性能和鲁棒性,并与其他的制导律进行仿真对比,其所需过载小,脱靶量小,易于工程实现.
