【Abstract】 For the case of a planar interception,a new guidance law with strong robustness is proposed.An adaptive variable structure guidance law is designed considering missile’s dynamics of autopilot,based on an adaptive trending-law of sliding-mode.The maneuvering acceleration of target is regarded as a disturbance with boundary,and the LOS(Line of Sight) angular rate is chosen as the output state to be controlled to zero in the guidance law.The algorithm is very simple,so it more convenient for comprehensible and practical implementation.The simulation results show that the algorithm has strong robustness and adaptability.更多还原
