Woo Jin Choi, Eunsil Lee, and Kyo-Beum Lee, "A Novel MPC-SVM Strategy for Direct Torque Flux Control of an Induction Motor Drive System Using a Matrix Converter," in Proc. ICIT Conf., Feb./Mar. 2014, pp. 181–186. > Paper

This paper proposes a model predictive control space vector modulation (MPC-SVM) method for the torque and flux controls of an

induction motor. The method to synthesize the reference voltage vectors according to pulse width modulation strategy and the

model predictive control method that directly uses the space vector modulation method of the conventional matrix converter are

described. 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 the induction motor

using only the MPC controller without a proportional-integral (PI) or hysteresis controller. Even though the proposed control 

algorithm is more complicated and has numerous computations compare to the conventional MPC, it can predict output voltages

of the matrix converter of the SVM method and synthesize the reference voltage vectors. This feature provides the reduction in

amount of calculations and the change of the control performance through the adjustment of prediction horizon N. The ​

proposed method confirms the validity using the PSIM simulation.
