Abstract: In the terminal guidance section of large caliber naval gun guided projectile (GP) while striking near shore maneuver targets, a terminal guidance law based on fuzzy adaptive approximation and dynamic surface control is proposed considering two order dynamic characteristics of autopilot and impact angle constraints. The relative motion model of GP and the target in two dimension is constructed, and the extended state observer is used to estimate acceleration of the target. Aiming at zeroing the tracking error about the line of the sight angle and angular velocity, the nonsingular terminal dynamic surface sliding mode is designed adopting the adaptive exponential reaching law. The fuzzy adaptive system is applied to approach variable structure term and weaken chattering of autopilot control instruction. The tracking error about the line of the sight angle and the angular velocity in the closed loop system are both uniformly bounded, which is proved by the Lyapunov second method. Simulation experiments show this terminal guidance law helps GP possess good terminal guidance performance while striking targets with different acceleration forms.
