船用电动伺服舵机性能仿真研究

摘要

To reduce the traditional hydraulic steering noise and improve the maintainability of the ships, an electro-servo rudder actuator program which mainly includes a DC torque electric motor and a harmonic gear was presented. The model of this actuator was established and the performance was simulated using MATLAB. The main factors which affected the performance of the rudder actuator were analyzed. The simulation results show the performance of this electro-servo rudder actuator can meet the steering requirements of the ship. The research results can be used to support the application of the electro-servo rudder actuator on ships.%为降低船舶传统液压操舵噪声及提高舵机的可维护性，提出一种船用电动伺服舵机方案，该方案主要由直流力矩电机和谐波齿轮组成。建立该舵机的模型，采用 Matlab软件进行性能仿真，并分析影响该舵机性能的主要因素。结果表明，电动伺服舵机的稳定性、精度、响应等性能可满足船舶的操纵要求，研究结果可为电动伺服舵机在船舶上的应用提供支撑。
