- As it is important to attack the targets with terminal angle constraint for a lot of guided weapons, an adaptive sliding mode guidance law is proposed based on the sliding mode variable structure control theory. Considering the problems that the terminal line of sight angle speed changes rapidly and terminal angle constraint, the guidance law chooses relative velocity deflection angle as the sliding mode surface, introduces terminal angle constraint, regards the target maneuvering as limited disturbance, and uses Lyapunov stability theory to analyze the stability of the guidance law. In order to weaken the chattering phenomenon of variable structure control, the guidance law proposes a new method that combining the variable switch term with saturated function. Finally, the designed guidance law is applied to the missile actual model to make a contrastive simulation, the results show that compared with the traditional method, the proposed guidance law can attack the target with less miss distance and terminal angle error, and has strong robustness.
