Influence of switching frequency on torque ripples in model predictive control of induction motor drive

The proper control of induction motor drive is an important task in many applications. Usually, the motor is supplied from voltage source inverter and the required voltage is calculated according to the actual and past states of the motor. Unlike this, the predictive methods calculate also the future state and adjust the voltage accordingly. The model predictive control method calculates the effects of all possible future states in the next step and chooses the best action according to desired criteria. In the paper, this method is employed in the induction motor drive and the influence of the switching frequency on the torque and flux waveform ripples are examined in simulation environment Matlab Simulink.
