采用永磁同步电机(PMSM)模拟螺旋桨的负载特性，建立推进电机、负载电机、螺旋桨特性数学模型，并设计了变 PI 转速调节器，控制推进电机。在此基础上，在 Maltab/Simulink 仿真环境下，搭建螺旋桨仿真系统模型。仿真结果表明，采用直接转矩控制的负载电机能很好地模拟螺旋桨的动态特性。该研究成果为船舶电力推进系统的后继研究奠定了前期基础。

In this article,a model of propulsion motor,propeller and load motor was established.This article also de-signed a variable PI speed controller to control the propulsion motor.On this basis,in the Maltab/Simulink simulation en-vironment,build the propeller simulation system.The simulation results show that the direct torque controlled load motor can well simulate the dynamic characteristics of the propeller.The results of this study laid the foundation for the subse-quent study of marine electric propulsion system.
