Integrated guidance/autopilot scheme for anti-vessel missiles based on three channels independence design idea

A scheme of integrated guidance/autopilot design for STT missile against maneuvering targets on the sea is proposed. Three channels independence design idea is adopted. Firstly, an integrated guidance/autopilot model of the yaw plane is formulated and the guidance/control law is designed based on the backstepping idea and variable structure control theory. Secondly, control laws are proposed for the height and roll angle, so that when a missile has the capability to hit the target on the yaw plane, and the height approaches zero as the distance between the missile and target on the yaw plane tends to zero, the missile will hit the target. Finally, to verify the effectiveness and rightness of the integrated design scheme, a simulation of some anti-vessel missile against high maneuvering targets was made and the results show that a high accuracy of hitting a target can be achieved.
