船舶电力推进永磁同步电机滑模变结构控制研究

摘要

在分析永磁同步电机(PMSM)的数学模型和磁场定向矢量控制的基础上，结合船-机-桨模型特征，对电机转速反馈环采用滑模变结构控制器，在 Matlab/Simulink 环境下搭建船舶推进电机控制系统仿真模型，通过实船数据给出仿真波形。仿真结果证明了滑模变结构控制器较强的鲁棒特性。%On the basis of permanent magnet synchronous motor (PMSM)mathematical model and analysis of field o-riented vector control,the paper combined boat-engine-propeller model features,used the variable structure controller in motor speed feedback loop,built maritime propulsion motor control system simulation model in Matlab/Simulink environ-ment,and gave the simulation waveform data through a real ship.The simulation results showed that the sliding mode con-troller has better robustness properties.
