摘　　要：永磁同步电机(PMSM)控制系统仿真建模在Matlab/Simulink环境下,通过对独立的PMSM本体、dq坐标系向abc坐标系转换、三相电流源逆变器、速度控制器等功能模块的建立与组合,构建PMSM控制系统的速度和电流双闭环仿真模型。仿真结果证明该模型的有效性,验证其控制算法,为PMSM控制系统的设计和调试提供基础。A novel method for modeling and simulink- ing the PMSM system based on Matlab is proposed. In Matlab/Simulink, the isolated blocks, such as PMSM block, which coordinates transformation from dq to abc block, three-phasec urrents ourcei nverterc ontroller block, speed controller block and ect,have been modeled.By the combination of these blocks,two control loops are used. which are the inner current-loop and the outer speed-loop. The reasonability and validity has been proved by the simu- late result and this novel method offers a new thought for designing and debugging actual motor.
