Space Vector Pulse Width Modulation BasedSpeed Control of Induction Motor using FuzzyPI Controller

Abstract

This paper presents design and implements a voltage source inverter type space vector pulse width modulation (SVPWM) for control a speed of induction motor. In recent years, the field oriented control of induction motor drive is widely used in high performance drive system.It is due to its unique characteristics like high efficiency, good power factor and extremely rugged .This scheme leads to be able to adjust the speed of the motor by control the frequency and amplitude of the stator voltage, the ratio of stator voltage to frequency should be kept constant.The fuzzy logic controller is also introduced to the system for keeping the motor speed to be constant when the load varies.
