基于Matlab的双三相PMSM建模与仿真

摘要

The mathematical model of the dual three-phase PMSM was analyzed,and the basic equation was given.The mathematical model of dual three-phase PMSM was established by the formulas in the six-phase stationary coordinate system,the two-phase stationary coordinate system and the two-phase rotating coordinate system.Then,in the simulation environment of Matlab/Simulink,each module of the dual three-phase PMSM was analyzed thoroughly and constructed.Finally,the established model was verified through the SVPWM control method,and the results prove the correctness of the established model.%分析了双三相PMSM的数学模型,并给出了其基本方程式,在此基础上,通过公式建立了双三相PMSM在六相静止坐标系、两相静止坐标系以及两相旋转坐标系下的数学模型,并且在Matlab/Simulink仿真环境中,详细分析并搭建了双三相PMSM各个模块.最后通过SVPWM控制方法对所搭建的模型进行了仿真验证,结果证明了所建立模型的正确性.
