Research on a method to reduce roll and pitch of AUV based on active bionic fin stabilizer

Autonomous underwater vehicles will invectively roll, pitch and heave heavily when they close to surface where there are waves, sea wind and ocean current. These disturbances influenced the normal working and safety of the autonomous underwater vehicles a lot. As anti-roll technology develops, a kind of active bionic fin stabilizer which can reduce roll and pitch effectively comes out. Hence this kind of active stabilization system is proposed to reduce the roll and pitch of the autonomous underwater vehicle when the autonomous underwater vehicle closes to water surface. From simulation results, it can be seen that active bionic fin stabilizer can effectively reduce roll and pitch of AUV under different wave encounter angle.
