The mathematical model was the foundation of the algorithm research of the motor servo loading system. T In this paper, a MATLAB/Simulink simulation model was established by mechanism modeling to facilitate the later algorithm research. The mathematical model of permanent magnet synchronous motor is deduced in detail, and the mathematical model of PMSM module, inverter module and SVPWM algorithm module was established. The MATLAB/Simulink simulation model of the motor was established by building a complete simulation model of the PMSM vector control system. The MATLAB/Simulink overall model of the electric servo loading system was established by coupling the intermediate connecting parts. Finally,the accuracy of the overall model of the motor servo loading system was verified through the simulations and experiments under the active and passive loading state of steps and sines, respectively.

Key words: motorized system, PMSM, SVPWM, Simulink, mathematical model, simulation
