Speed Control of Induction Motor using Fuzzy PI Controller Based on Space Vector Pulse Width Modulation

The aim of this paper is that it shows the dynamics response of speed with design the fuzzy logic controller to control a speed of motor for keeping the motor speed to be constant when the load varies. 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 paper presents design and implements a voltage source inverter type space vector pulse width modulation (SVPWM) for control a speed of induction motor. This paper also introduces a fuzzy logic controller to the SVPWM in order to keep the speed of the motor to be constant when the load varies. FLC is used to control the pulse width of the PWM converter used to control the speed of the motor.
