The Fuzzy-PID controller of fin stabilizer was designed based on fuzzy control and PID control theory. The controller of Fin Stabilizer is designed which uses roll angle and angular velocity of roll angel as input and fin angel as output. The model of ship is built based on Conolly theory. The controller is simulated using MATLAB. Results shows that compared with conventional PID controller, the FUZZY-PID controller has better effect.

设计了基于模糊控制和PID控制理论的FUZZY-PID复合控制减摇鳍控制系统，以横摇角和横摇角速度为输入量，鳍角为输出量，基于Conolly理论建立了船舶模型，利用MATLAB针对不同海情对控制器进行了仿真，结果表明减摇鳍模糊控制器动态响应性能和稳态控制精度均十分理想，能够满足减摇鳍控制系统的控制要求。
