Abstract—considering the disadvantages of torque ripple and
current distortion on traditional direct torque control (DTC) of
induction motor, a new direct torque control strategy based on
predicting the stator voltage vector is presented in this paper.
The stator voltage prediction control scheme estimates the
desirable stator voltage of the next cycle by the current state
value and the desirable flux and torque. With the use of space
vector pulse width modulation (SVPWM), the inverter’s
switching control signal is obtained. Simulation results are
presented to verify the effectiveness of this strategy. Based on
this, the strategy was applied on the induction motor speed
regulation experiment platform based on TMS320F2812DSP,
and achieved good performances.
