Abstract

This paper presents a comparative study on speed control of BLDC motor using various controlling techniques. Speed control of BLDC motor can be achieved by estimating different parameters such as rotor speed, position and phase-to-phase BEMF and torque through DTC, P, PI& PID control, Fuzzy logic PI control, CCSVM based control and sliding mode control. Now a day the demand of BLDC motor increases due to their high efficiency, simpler structure, better controllability and large torque to inertia ratio compared to BLAC motors. In many applications, obtaining a low-frequency ripple-free torque and instantaneous torque and even flux control are of primary concern for BLDC motors with non sinusoidal back-EMF. It is very much essential to propose a study to know about the effectiveness of the control methods employed for BLDC motor drives. Hence a theoretical study is developed and the results obtained by simulation are presented to show the effectiveness of the various methods.
