| 摘 要： | 为解决船舶电力推进系统在螺旋桨负载受到风浪干扰时的稳定性问题,采用永磁同步电动机(Permanent Magnet Synchronous Motor,PMSM)作为推进电动机,在空间矢量调制(Space Vector Modulation,SVM)方法和直接转矩控制(Direct Torque Control,DTC)方法的基础上,提出一种基于滑模变结构的SVM-DTC方法.通过Simulink搭建模型进行船舶工况仿真,对推进电动机的转速和电磁转矩进行分析.仿真结果表明采用滑模控制的船舶电力推进系统具有很好的静态、动态特性和鲁棒性.

| Abstract: | To improve the stability of the ship electric propulsion system when the propeller is suffering wind and wave disturbance, Permanent Magnet Synchronous Motors (PMSMs) are used as propulsion motors, Space Vector Modulation (SVM) method and Direct Torque Control (DTC) method are considered, and the sliding mode based SVM DTC method is proposed. A model is constructed to simulate different working conditions of ships by Simulink, and the rotational speed and the electromagnetic torque of propulsion motors are analyzed. The simulation results prove that the ship electric propulsion system based on sliding mode control is of good static and dynamic characteristics and robustness. |
