Robust Guidance of Missile Against Maneuvering Target Based on Sliding-Mode Guidance Law

기동표적에 대한 슬라이딩 모드 유도법칙을 이용한 미사일 강인유도

The optimal guidance has advantages of accuracy and economic energy consumption but it is difficult to implement due to its dependence on the target information such as the relative range, the relative velocity and the acceleration of target. This paper uses optimal guidance and sliding-mode guidance to obtain a new guidance method. The suggested method shows robustness against target maneuvers, good dynamic performance, energy saving of missile and terminal accuracy. Its effectiveness is demonstrated by the simulation results.
