This paper proposes a MPC (Model Predictive Control) method for the torque and flux controls of induction motor. The proposed

MPC method selects the optimized voltage vector for the matrix converter control using the predictive modeling equation of the

induction motor and cost function. Hence, the reference voltage vector that minimizes the cost function of the torque and flux error

within the control period is selected and applied to the actual system. As a result, it is possible to perform the torque and flux control

of induction motor using only the MPC controller without a PI (Proportional-Integral) or hysteresis controller. Even though the

proposed control algorithm is more complicated and has lots of computations compared with the conventional MPC, it can perform

torque ripple reduction by synthesizing voltage vectors of various magnitude. This feature provides the reduction of amount of

calculations and the improvement of the control performance through the adjustment of the number of the unit vectors n. The

proposed control method is validated through the PSIM simulation.
