(To provide the necessary design parameters for the actual motor control system, the modeling course of
voltage space vector pulse wide modulation(SVPWM)agrithmetic and AC motor under Matlab/Simulink environment
are introduced. The dynamic model of variable frequency speed regulating system based on vector control is
discussed according to the principle of SVPWM. The new method of realizing simulation, key problems and
results of the simulation are analyzed in detail. The experimental simulation results show that this system has
smaller fluctuations of voltage and torque, quicker response speed, and all of the indicators accord with the
performance of the actual motor. The simulation agrithmetic have value to realize controlling motor with digital
signal processing.
