In this paper, predictive current controller (PCC) is implemented for controlling voltage source inverter (VSI) for a feedback linearization controlled (FLC) induction motor (IM) drive for better rotor speed and torque dynamics. Two new control inputs are developed using output of Proportional Integral (PI) controllers which regulate the rotor flux and rotor speed. Reference currents are the input to the PCC. The PCC regulates stator current of the IM according to the generated reference signal received. Error between predicted stator currents and reference current generated using control algorithm is minimized using the cost function defined in PCC. The best switching state which gives the minimum value of cost function is selected and applied to the switches of the three-leg VSI without any use of modulation stage and linear regulators. The proposed method is validated using MATLAB/Simulink for different operating points.
