Based on adaptive fuzzy approach strategies and dynamic surface sliding mode control techniques, a novel interception guidance law is proposed for the problem that a missile attacks a high maneuvering target. Relative motion equations of missile and target are established accounting for autopilot lag. Based on the annihilating idea of the missile-target LOS (line-of-sight) angular velocity, a dynamic surface sliding mode guidance law is designed with adaptive reaching law. Meanwhile, the adaptive fuzzy method based on integrated the LOS angular velocity and missile-target distance is adopted to approach variable-structure term. The simulation results show that this law can remove chattering phenomenon. Moreover, this law has higher guidance precision to high maneuvering.
