Abstract

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.
