In this paper, a mathematical model of PMSM is analysed using the dominant simulation modelling capabilities of MATLAB/SIMULINK. One of the most efficient control strategies of PMSM is Vector control. There are several independent functional module, such as coordinate transformation module, PMSM body module, inverter module, controller modules, and some other modules which play an important role in controlling of PMSM. The combination of these modules results in simulation model of the PMSM control system. The model has many advantages in simulation. The detailed structure of the simulation model in MATLAB/SIMULINK is presented. Finally, a simulation example is proposed to verify the feasibility.
