摘　　要：船舶加装减摇鳍目的是减小船舶的横摇运动.鳍的运动通过由PID控制的液压装置驱动.文章考虑了船舶的粘性阻尼系数,结合减摇鳍运动特性,通过PID控制法对加装减摇鳍船舶横摇进行预报并通过实船验证.The aim of nsing roll stabilizer fins on ships is to reduce the roll motions. The fins are controlled by electro-hydraulic mechanism based on PID control algorithm. This paper considers the viscous damping coefficient of ships and combines the characteristics of the fin motion, and predicts the ships with fins roll motions using PID control algorithm, and its real ship experiment passes.
