Vector Control Simulation of Asynchronous Motor Based on SVPWM

A vector control method of three-phase asynchronous motor with voltage space vector pulse width modulation SVPWM applied to a large electric wheel mine car is studied. First of all, the mathematical model of asynchronous traction motor is derived according to the coordinate transformation theory, and the basic principle of SVPWM control technology is analyzed, and the simulation algorithm is obtained. Combined with the algorithm, the model of AC motor double-closed-loop speed regulation system is built on MATLAB/SIMULINK. The simulation results show that the motor speed tracking ability of the control method is strong. It has good dynamic and steady state performance and strong practicability and accuracy.
