Comparative Analysis of BLDC motor for different control topology

Abstract

This paper presents comparative analysis of trapezoidal shaped back emf Brushless DC motor (BLDCM) for different control topology. The power Quality (PQ) indices like Total Harmonic Distortion (THD), Crest Factor (CF), Power Factor (PF) across the supply mains are to be analyzed and to ensure within the limits prescribed by International standards. To combat PQ menace, the performances of three controllers. Viz., PI, Fuzzy, and Hybrid are to be compared with respect to the following parameters maximum overshoot (Mp), setting time (Ts), Rise time (Tr) and steady state error (Ess) Hence it is a novel attempt because motor parameters speed and torque ripple, PQ indices and controller parameters are analyzed simultaneously. This Proposed technique is executed in simulink of MATLab software of a BLDC Motor.
