This paper presents an improved predictive control of an induction machine fed by a matrix converter using N-switching vectors as

the control action during a complete sampling period of the controller. The conventional model predictive control scheme based

matrix converter uses a single switching vector over the same period which introduces high torque ripple. The proposed switching

scheme for a matrix converter based model predictive control of an induction machine drive selects the appropriate switching vectors

for control of electromagnetic torque with small variations of the stator flux. The proposed method can reduce the ripple of the

electrical variables by selecting the switching state as well as the method used in the space vector modulation techniques. Simulation

results are presented to verify the effectiveness of the improved predictive control strategy for induction machine fed by a matrix

converter.
