Guidance law with angular constraints for head-pursuit or head-on engagement

  • 摘要: 针对逆轨、顺轨拦截模式,提出了带末端约束碰撞角的ACPN(Angle Control Proportional Navigation)、ACRPN(Angle Control Retro-Proportional Navigation)2种轨迹成型制导律.将线性的比例制导(PN)/负比例制导(RPN)作为标称指令,将碰撞角约束作为反馈指令,以相对加速度建立微分方程,得到了ACPN、ACRPN制导律.ACPN使用正比例系数,逆轨拦截目标;ACRPN使用负比例系数,顺轨拦截目标.与现有的研究结果进行仿真对比:ACPN具有耗费控制力少、末加速度小的优势;ACRPN的控制力、脱靶量、碰撞角误差较逆轨拦截优势明显.此外,分析了拦截高速目标的捕获区域.结果表明,ACPN比偏置比例导引的捕获区域大.当拦截弹的航迹角小于π/2+λi时(λi为初始视线角),宜采用ACPN(逆轨模式)拦截目标,拦截弹的航迹角大于等于π/2+λi时,宜采用ACRPN(顺轨模式)拦截目标.
