Research of adaptive fuzzy controller in pitch regulation system of ocean submarine

The kinematics model and control method for pitch regulation system of ocean submarine is mainly studied in this paper. By building model for revolving inclined tray of positional reverse decoupling, the control rule of pitch regulation mechanism can be get, by three hydraulic cylinder servo system driving, so the movement of inclined tray and pitch of blade can be controlled, and then variable vector propeller can be controlled. Adaptive fuzzy controller is fuzzy logic system with learning arithmetic, which can get adaptive control effect based on only knowing fuzzy information of system and not knowing accurate mathematic model of system, so the system achieved a nicer control effect.
