摘　　要：在M atlab/S im u link环境下,通过对独立的PM SM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建立与组合,构建了永磁同步电机控制系统的速度和电流双闭环仿真模型。验证了其控制算法。仿真结果证明了该系统模型的有效性,为永磁同步电机控制系统的设计和调试提供了理论基础。A novel method for modeling and simulink of PMSM system in Matlab is proposed. In Matlab/Simulink, the isolated blocks,such as PMSM block,coordinate transformation form d/q to a/b/c block,Three phase current source inveter controller block,speed controller block ,etc. ,have been modeled. By the organic combination of these blocks ,two control loops are used. ,which are the inner current-loop and the outer speed-loop. The reasonability and validity have been testified by the simulate result and this novel method offers a new thought for designing and debugging actual motor.
