摘　　要：在分析零航速减摇鳍升力特性的基础上,推导出了减摇鳍动态流体力矩和平均横摇角速度的计算方法,提出了通过转鳍动态流体力矩和平均横摇角速度计算伺服系统驱动功率的方法。同时根据计算所得的伺服系统驱动功率进行了电动伺服系统的仿真实验。实验结果表明,采用动态流体力矩代替静态流体力矩计算所得的伺服系统驱动功率更加精确、合理,提高了系统的工作效率。The expressions on dynamic hydro-torque of fin stabilizer and average angular velocity of roll movement are derived by analyzing the lift characteristic of fin stabilizer at zero speed. And then a theoretic method to calculate the driving power of servo system is presented. Simulated expriment is carried out based on the driving power gained in this method. Expriment results indicate that the driving power of servo system derived from dynamic hydro-torque is more accurate and reasonable than that derived from static hydro-torque. As a result, the efficiency of system is enhanced.
