SVPWM Based Stator Oriented Non-linear Control of Induction Motor Drives

L. Pradeep Raja, R. Balasubramanian, K. Parkavi Kathirvelu and Rengarajan Amirtharajan    

Abstract: This study presents a new Space Vector Pulse Width Modulation (SVPWM) based stator oriented non-linear control of induction motor drive system using MATLAB/Simulink environment. The non-linear control is employed in the stator by making a small change in the variable transformation and this control technique will not affect the system dynamics and improves the performance in all four quadrants. This reduces size and cost of the induction motor drive system. The steady state and transient response of the drive system is observed in all the four quadrants and their torque and speed characteristics were studied. This non-linear control in this system is better compared to other systems. The motor drive is simulated in all four quadrants and their waveforms were plotted.
