摘要/Abstract

摘要： 针对临近空间高超声速滑翔目标的拦截问题,提出了基于衰减记忆滤波算法的滑模中制导律。基于当前统计模型衰减记忆EKF(Extended Kalman Filte)算法获取精确的高超声速目标运动参量;基于滤波信息和滑模控制理论,设计了随目标机动规律在线调节拦截弹道的滑模中制导律。仿真结果表明,该衰减记忆滤波算法可以对滑翔目标进行有效跟踪且滤波精度较高;针对滑翔目标的多种机动模式,所设计的中制导律可以实现在稳定跟踪目标的同时避免始终紧随目标机动,降低过载需求。所提出方法具有良好的制导性能和较强的鲁棒性。

Abstract: Aiming at the interception of hypersonic gliding target in near space, a sliding mode guidance law based on fading memory filtering algorithm is proposed. The accurate motion parameters of the hypersonic target are obtained based on the current statistical model fading memory EKF(Extended Kalman Filter) algorithm. Based on the filtering information and sliding mode control theory, a sliding mode guidance law is designed to adjust the interception trajectory online according to the target maneuver law. The simulation results show that the proposed fading memory filtering algorithm can effectively track the gliding target with high filtering accuracy. For a variety of maneuvering modes of the gliding target, the designed midcourse guidance law can achieve stable tracking of the target while avoiding always following the target maneuver to reduce overload requirements. Monte Carlo results show that the proposed method has good guidance performance and strong robustness.

Key words: fading memory filter, midcourse guidance, near space, hypersonic gliding target
