Analysis of Torque Ripple in Vector Control of BLDC Motor using SVPWM Technique

Industrial generally needs low oscillations in motor output. As compared to other motors the BLDC motor has more advantages and used in more applications. The torque ripples and speed control in motors are playing a key role in application. So definitely, there is a need to reduce the oscillations and control the speed in closed loop operated BLDC motors. This paper presents the PI, fuzzy controller for reducing the torques ripples and also for speed control of BLDC motor. Pulse width modulation (PWM) generation and subsequent switching can reduce oscillations in torque content. For accurate results mathematical modelling is required to design in simulation model. The simulation models of mathematical modeling, Space vector Pulse width modulation operated BLDC with PI & fuzzy control and the results are also presented.
