【摘要】 提出了永磁同步电机(PMSM)控制系统仿真建模的方法,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,构建了永磁同步电机控制系统的速度和电流双闭环仿真模型.仿真结果证明了该系统模型的有效性,验证了其控制算法,为永磁同步电机控制系统设计和调试提供了理论基础.更多还原

【Abstract】 A novel method for modeling and simulink of PMSM system based on Matlab is proposed.In Matlab/Simulink,the isolated blocks,such as PMSM block,coordinate transformation block from dq to abc,three phase (current) source inverter controller block,speed controller block etc.,are modeled.By the (functional) combination of these blocks,two control loops are used,which are the inner current-loop and the outer speed-loop.The reasonability and validity are testified by the simulation and this novel method offers a new thought for the design and test of actual motors.更多还原
