Abstract: This article is studied on currently a very active field of researching sinusoidal pulse width modulation (SPWM) frequency speed control system, and strengthen researched on the simulation model of speed control system with MATLAB / Simulink / Power System simulation tools, thus we can find the best way to simulation. We apply it to the actual conveyor belt, frequency conversion motor, when the obtained simulation results are compared with the measured data, we prove that the method is practical and effective. The results of our research have a guiding role for the future engineering and technical personnel in asynchronous motor SPWM VVVF CAD design.


Keywords: Simulation analysis, MATLAB/ Simulink / power system, Variable frequency speed control, Sinusoidal pulse width modulation, Asynchronous AC motor.
